UWB技术在移动式多媒体教学中的应用可行性研究
摘要
超宽带(Ultra-Wideband,UWB)技术已逐渐成为无线通信领域研究与开发的热点,并被视为下一代无线通信的关键技术之一。UWB无线通信系统具有信道容量大、辐射功率谱密度低、抗多径能力强、收发机结构简单和保密性好等优点。在频谱资源日益紧张、传输速率要求不断提高的今天,超宽带无线通信为高速率无线通信提出一种新的解决方案,尤其适用于室内多径环境中的短距离无线通信。
本文根据文中的研究结论,设计了基于FCC指定的UWB无线通信系统标准及IEEE802.15.3a信道模型的Ad-Hoc网络。该网络模型采用有限状态机(FSM)来描述整个系统的逻辑行为。利用该模型进行仿真实验,对该系统中网络负载、端对端时延、MAC层访问延时、丢包率等网络通信参数进行详细分析,并给出各个参数的性能曲线图。通过对该系统仿真实验结果的分析,我们得出结论,采用DS-UWB技术建立的移动式多媒体教学网络,在各方面的系统性能都能够满足移动式多媒体教学网络的多媒体教学资源实时传输业务的要求,具备改变当前的移动式多媒体教学现状的能力。
本文的创新点在于,在分析现有移动学习平台的基础上,提出了将移动式多媒体学习系统与UWB无线通信技术相结合,并根据多媒体教学的要求以及UWB无线通信的技术参数建立了一个移动式多媒体教学网络的仿真环境并进行了仿真。根据无线多媒体数据传输的QoS参数,对该基于该仿真环境的实验结果进行了QoS分析,并证明,将UWB技术引入到移动式多媒体教学当中能够满足移动式多媒体教学的需求。
同时,根据多方面调查结果,目前国内外还没有将UWB无线通信技术引入到移动式多媒体教学的案例。
UWB (Ultra-Wideband UWB) wireless technique has become a hot research issue and development of the wireless communication field, and has been seen as the next generation of the wireless technique. UWB wireless communication systems have channel capacity, low-power spectral density of radiation, anti-multipath, and a strong ability transceiver simple structure and confidentiality of the proposed method. Increasingly tense in the spectrum resources, transfer rates rising today, UWB wireless communication to high-speed wireless communication as a new solution, particularly suitable for indoor multipath environment in the short-distance wireless communications.
According to the the conclusion of this paper, based on the design of the FCC designated UWB wireless communication system standards and IEEE 802.15.3a channel model, The network model using finite state machine (FSM) to describe the logic of the entire system. We took simulation experiments with this model, the system load, end-to-end delay, the MAC layer delay, packets loss rate, and other network communication parameters detailed analysis, and gives the performance of each parameter curves. Simulation of the system through the analysis of experimental results, we concluded that the use of DS-UWB technologies for mobile multimedia teaching network, and the various aspects of system performance can meet the mobile multimedia teaching resource network of real-time transmission of multimedia teaching business request, and has the ability of making changes to the current status of mobile multimedia teaching.
In this paper, the innovation lies in the analysis of existing mobile learning platform on the base of the proposed mobile multimedia learning system with the UWB wireless communications technology, and in accordance with the requirements of multi-media teaching UWB wireless communications, as well as the technical parameters of the establishment of a mobile multimedia teaching network simulation environment and simulation. According to wireless multimedia data transmission QoS parameters, the simulation environment based on the experimental results of the QoS analysis, and that will be UWB technology into mobile multimedia teaching them to meet the mobile multimedia teaching needs.
At the same time, according to various survey results inland and abroad will be no introduction of UWB wireless communications technology using in the mobile multimedia teaching case.
