摘要
无线接入凭借其无处不在、灵活快捷的接入方式已经在人们工作和娱乐生活中扮演越来越重要的角色。随着iPhone/iPad等个人终端设备的流行,以及三网融合、物联网等国家新兴战略产业的兴起,无线通信容量需求将会骤增并对现有无线接入技术提出严峻挑战。另外,随着电信运营商部署建设的通信基站数目不断增加,且基站所占的功耗通常高达70%以上,这将导致蜂窝移动通信面临难以解决的能耗危机。目前中国移动正在大力研发的C-RAN就是要构建基于集中化处理、协作式无线电和实时云计算的绿色无线接入网构架,其中集中化是很重要的一个特点,需要实现中心局(CO)和远端天线单元(RAU)的分离。光载无线(ROF)系统是微波光子学在发展历程中的重要应用形式和价值体现,在未来宽带光纤接入和无线接入融合演进的潮流中发挥着重要作用。ROF系统利用光纤低损耗和高带宽的传输特点,通过模拟光纤链路实现CO和低成本RAU的分离,并构建广覆盖、低能耗和高带宽的动态可控的分布式天线系统,是解决当前无线接入技术中存在的带宽危机和能耗危机等问题的有效途径。
论文瞄准动态可控ROF系统在宽带泛在接入中的应用需求,针对在模拟光纤链路性能和射频资源动态可控两方面所遇到的技术挑战,重点进行射频光传输和射频光调控技术的研究。论文以模型为基础,以关键技术为支撑,以应用为目标,紧密围绕ROF系统模型、射频光传输与调控关键技术、ROF系统应用三个层面开展研究工作,其具体研究内容和贡献如下：
(1)ROF系统模型
高性能模拟光纤链路是ROF系统在宽带接入和泛在感知应用中的重要保障,要分析和提高链路性能,则建模是首要工作。论文从微波放大器模型出发,建立了直调和外调ROF系统中主要性能指标的数学模型,并分别仿真分析了探测器接收光功率、直调激光器(DML)相对强度噪声(RIN)、外调制器的半波电压和注入光功率对链路性能指标的影响。该工作为高性能ROF系统设计和优化提供了理论基础。
无论是利用受激布里渊散射(SBS)效应实现射频移相,还是抑制其对ROF链路性能造成的不利影响,均需要熟悉SBS效应的产生机理并精确测量其增益谱和损耗谱。论文提出了一种基于菲涅尔反射和抑制载波调制的高精度SBS增益谱/损耗谱的测量方法,优点有：单端测量,避免光源频率抖动引入误差的同时,也能应用于低成本的光纤传感中；精确测量,通过微波源的扫频来获取SBS谱线,因而具有1MHz以下的测量精度；器件带宽低,仅需要SBS频移一半带宽的器件即可。
(2)射频光传输关键技术
针对复杂拓扑结构下的组网需求,论文提出了一种基于粗波分复用(CWDM)方式的分布式射频光传输系统并对链路性能进行了实验研究,搭建了五路波长复用的ROF分布式WiFi系统,支持5个RAU,在光纤传输距离为4.5kin和22km条件下分别获得约为1.5%和2.5%的误差矢量幅度(EVM),无线环境下在4m传输距离时得到最佳传输性能。对激光器RIN参数的研究发现,当大于-125dBc/Hz时对EVM影响较大。
针对毫米波频段ROF系统的应用需求,论文提出了一种基于直调和外调抑制载波(OCS)方式的吉比特光载毫米波技术,采用直调激光器完成基带数据的调制并产生光载波,极大程度降低了系统成本,实验完成了2.4GHz直调信号到32GHz毫米波信号的上变频,并利用VPI8.7平台仿真了DML的RIN参数对链路性能的影响。
为满足宽带射频信号调制需求,论文首次提出了一种基于相位调制-强度调制(PM-IM)转换的全光射频BPSK调制与传输技术,该技术以光学单边带的方式在光纤中传送信号,不仅抑制了光纤色散的影响,也通过多波长单边带的产生使其满足在波分复用(WDM)ROF系统中的应用需求。针对其在实验中的稳定性问题,利用同样原理引入调频光源和带通滤波器并通过Optisystem7.0对链路性能进行仿真,获得眼图较好的波形,且误码率达到6×10-9。
抑制SBS效应是实现高性能ROF系统的重要环节,论文实验研究了激光器线宽对SBS阈值以及链路性能的影响,测试了WiFi信号在直调和外调链路中的传输性能以及光功率监测情况,发现光源线宽为10MHz的直调模式对应的SBS阈值比光源线宽为50KHz外调模式的阈值增加了4dB,证实了激光器线宽展宽在抑制SBS效应中起到的积极作用。
(3)射频光调控关键技术
针对动态可控ROF系统在射频带宽资源管控方面的应用需求,论文利用基于MEMS光开关矩阵的射频切换技术来实现射频带宽的动态分配。为分析光开关矩阵给链路性能带来的影响,测试了4×4光开关的切换速率,以频谱方式测出光开关切换的效果,并给出EDFA增益和光开关矩阵损耗对链路EVM的影响。基于光开关矩阵的射频切换技术不仅能够实现无线覆盖小区的资源交换,而且可以实现组播业务,为ROF系统的智能化奠定基础。

(4)ROF系统在宽带接入和泛在感知中的应用
在WiFi大规模应用的形势下,以无线局域网(WLAN)作为宽带中继网络,无线传感网(WSN)与WLAN结合的异构网络架构成为未来物联网中极具潜力的接入技术之一。论文在该背景下提出了一种基于CWDM-ROF系统的异构WLAN和WSN网络,在实验室环境下搭建了面向宽带接入和泛在感知应用的光载VViFi分布式天线系统,并演示了包括宽带接入、温度传感、视频监控和RFID定位等业务。

The wireless access technology has played a more and more important role in the human lives due to its advantages of ubiquitous and flexibility. With the popularity of the personal terminals such as iPhone/iPad, and the rise of the national high-tech industry, the increasing requirement for wireless capacity brings forward grave challenge to the existing wireless access technologies. Furthermore, with the increasing of base stations (BS) implemented by the telecommunication operators, more than70%of the total energy is consumed by the BS and leads to an energy crisis in the cellular mobile communications. At present, C-RAN is intensively developed by China Mobile and aims to construct a clean system based on the centralized processing, collaborative radio and real-time cloud infrastructure, among which the centralized processing requires the separation of remote antenna units (RAUs) from the central office (CO). As one of the most important applications of the Microwave Photonics (MWP), radio-over-fiber (ROF) systems play an important role in the evolution of the convergence between broadband fiber access and wireless access. ROF systems make full use of the advantages of fiber transmission such as low loss and broad bandwidth to realize the separation of RAUs from CO, and build dynamic controllable distributed RAUs systems with wide coverage, low energy and broad bandwidth, thus it becomes an effective solution to the bandwidth crisis and energy crisis existed in the present wireless technologies.
In order to meet the application requirement of dynamic controllable ROF systems in the broadband ubiquitous wireless access, and resolve the technical challenge in analog-optic fiber link performance and RF resources controlling, this thesis mainly studies the RF-optic transmission (RFOT) and operation (RFOO) technologies, and most of the work is concentrated on the modeling, RFOT&RFOO technologies and the applications of the ROF systems. The detailed content and contributions are presented as follows:
(1) Modeling of the ROF Systems
The analog-optic fiber link with high performance is necessary for the application of ROF systems in the broadband access and ubiquitous sensing, and the modeling is the priority to analyze and improve the link performance. This thesis builds a mathematic model of the main performance indexes in the direct and external modulated ROF systems based on the microwave amplifier model, and analyzes the impact of the parameters, such as the received optical power of photodetector (PD), relative intensity noise (RIN) of direct modulated laser (DML), half-wave voltage and injected optical power of the external modulator, on the link perfonnance indexes by simulation.
Characterization of stimulated Brillouin scattering (SBS) gain and loss spectra is necessary not only in the application but also suppression of the SBS effect in ROF systems. This thesis proposes a simple and precise method to characterize the SBS gain and loss spectra based on the Fresnel reflections and optical carrier suppressed (OCS) modulation, which owns the advantages such as single-ended structure to prevent the error due to laser frequency fluctuation, precise measurement with1MHz or higher resolution due to the small-step sweeping of microwave sources, and low-cost components with bandwidth being half of the Brillouin shifted frequency.
(2) RFOT Technologies
In order to meet the requirement of networking with complex topology, the thesis proposes a distributed RFOT system based on the coarse wavelength division multiplexing (CWDM) ROF technique and builds a CWDM-ROF based distributed WiFi system with five wavelength channels, which supports5RAUs, and achieves approximate1.5%and2.5%of the error vector magnitude (EVM) for4.5km and22km single mode fiber (SMF) transmission, respectively. The best transmission performance is obtained when the wireless distance is4m. The impact of the laser RIN is also studied and EVM is degraded obviously when RIN>-125dBc/Hz.
For application requirement of millimeter (mm) wave band ROF systems, the thesis proposes a gigabit-level mm-wave over fiber technique based on direct modulation and external OCS modulation. The DML is used to generate optical carrier and modulate the baseband data which greatly reduces the system cost. Up-con version of2.4GHz to the32GHz mm-band is demonstrated experimentally and the impact of DML RIN on link performance is studied on the VPI8.7platform.
In order to realize broadband RF modulation, the thesis firstly proposes an all-optical RF BPSK modulation and transmission technique based on phase modulation to intensity modulation (PM-IM) conversion. The multi-wavelength single sideband (SSB) signals are generated which can tolerate fiber dispersion and meet the requirement of WDM-ROF applications. Considering the stable issue in the experiment, the frequency modulated (FM) laser and band pass filter (BPF) is employed to accomplish the performance simulation on the Optisystem7.0, which achieves good waveform with wide eye diagram and bit error rates of6×10-9.
The impact of laser linewidth on the SBS threshold and link performance is also studied in the thesis. EVM of WiFi signals is measured in the direct and external modulated ROF links, and the optical power is monitored accordingly. The SBS threshold is improved by4dB when the50KHz-linewidth external modulated link is replaced by the lOMHz-linewidth direct modulated link, which confirms the laser linewidth broadening for the suppression of SBS effect in ROF systems.
(3) RFOO Technologies
Dynamic controllable ROF systems can improve the efficiency of the RF bandwidth resources, thus the thesis proposes an RF switching technique based on the MEMS optical switch matrix (OSM) in order to realize the dynamic allocation of the RF bandwidth. Switch speed of the4×4MEMS OSM is measured, and the RF switching is observed by monitoring the optical spectra. The impact of the loss of the OSM on the system EVM is studied experimentally with the help of the Erbium doped fiber amplifier (EDFA). This OSM-based RF switching technique can not only realize the RF resources allocation but also provide multicast services which make the ROF system intelligent.
RF phase shifter is the key component in the beamfonning of both smart antennas and optical controlled phase-arrayed radars. The thesis firstly proposes a photonic RF phase shifter based on SBS effect and vector-sum theory. PM-IM conversion is completed with the help of SBS functioned on the PM-generated two sidebands. At PD, the two sidebands are mixed with the optical carrier and generate the RF signals with controllable phase shift.
(4) Applications of the ROF Systems
With popularity of the WiFi techniques, a hierarchical architecture of wireless sensor network (WSN) and wireless local area network (WLAN) provides a promising solution to the Internet of Things (IOT). In this thesis, a new hierarchical architecture is proposed for ubiquitous wireless sensing and access with improved coverage using CWDM-ROF links. The demonstration platform is built to provide multi-services, such as broadband access, temperature sensing, video monitoring and RFID location, etc.
In order to meet gigabit-level wireless access requirement, the thesis proposes a multi-band (2.4GHz WiFi and60GHz mm-wave band) dynamic controllable ROF system architecture for in-building multi-services integrated access. The ubiquitous WiFi channel is used for the uplink of60GHz-band ROF link which greatly reduces the cost. The dynamic controllable ROF system is used to realize the bandwidth allocation based on the OSM RF switching techniques. Finally, the distribute antenna system with bandwidth dynamic allocation is implemented, which can not only provide gigabit-level un-compressed high definition television (HDTV) services, but also meet the intelligent house services, such as ubiquitous Mb/s-level access, security surveillance, environment monitoring, etc.
