中继蜂窝网络中的协作分集研究
|
摘要
传输的可靠性和有效性是衡量无线通信系统性能好坏的两大指标。协作分集技术能够克服多径衰落,有效的改善系统传输的可靠性。网络编码可以提高无线通信系统的资源利用率。因此,如果能够有效的结合协作分集技术和网络编码技术,将可以改善无线通信系统的总体性能。
本文主要探讨了在蜂窝网络系统中,如何有效的结合协作分集和网络编码的优点,在获得分集增益的同时也能获得网络编码增益。首先提出适用于上行链路的网络编码协作分集方案,核心思想就是赋予中继具有对来自不同用户的信息进行网络编码的功能。我们给出具体的接收端译码方法,并且对中断行为进行了分析。仿真结果表明,和传统的译码协作分集相比,在高信噪比下,网络编码协作分集可以使用更少的频谱资源,获得更低的中断概率。
接下来,针对下行链路的特点,本文提出多中继的网络编码协作分集和增强型的网络编码协作分集方案。多中继的网络编码协作分集方案中,相邻中继对重叠区域内的用户,联合进行网络编码。增强型的网络编码协作分集方案中,中继节点根据源节点和目的节点以及源节点和中继节点之间的链路状况,决定是否进行协作通信和协助转发数据的方式是网络编码转发、译码转发或者放大转发。该方案结合了网络编码和增强性中继的优点,能进一步提高无线通信系统的可靠性和有效性。
最后,本文提出基于网络编码协作分集技术的切换方案。在方案中,我们充分利用网络编码协作分集技术的特点,以增加不多的时隙资源来完成扇区之间的切换,能够大大降低系统资源和性能指标之间的矛盾。
Transmission reliability and efficiency are two targets of the wireless communication system. Cooperative diversity technology can overcome the multipath fading and improve the effectiveness of system transmission. Network coding can improve the utilization rate of spectrum in wireless communication system. The combination of cooperative diversity and Network coding can improve the overall system performance dramatically.
This article researches that how to apply the network coding theory in cooperative diversity technology to acquire the diversity gain and network-coding gain simultaneously. Firstly, we propose a network-coded cooperative diversity plan on uplink, whose core idea is to give the network coding function to relay node. We give out the concrete decoding method and analysis the interruption behavior. Simulation results shows that compared to traditional way, network-coded cooperative diversity technology uses less spectrum resources and acquires lower interruption probability in.high signal noise rate (SNR).
Next, we propose a multi-relay network-coded cooperative diversity plan and an enhanced network-coded cooperative diversity plan. In the first plan, neighboring relays in the interleaved area make joint network coding with information. In the later plan, relays decide whether to communication coordinately and which forward mode will be used, network-coding forward, decoding forward or amplify forward. This plan combines the advantage of network coding and enhanced relay, which can improve the reliability and efficiency of wireless communication system.
Lastly, we propose a handover plan based on network-coded cooperative diversity technology. In the new plan, we make best use of the advantages of network-coded cooperative diversity, and add more time slot resources to fulfill the handover process between sectors, so we can reduce the conflicts between system resource and performance.
