首先给出了二进制删除中继信道下基于喷泉编码的多种协作方案,并依性能得出了最优方案,此后借鉴渐近最优喷泉编码的概念,将该最优协作方案扩展到无线中继信道中,并利用排队理论实现了中继节点的最优流量控制,给出了无线中继信道下的中继流控制协作方案。仿真结果表明,基于喷泉编码的中继信道协作方案有效地解决了中继缓存溢出问题,提高了信道的可达速率。
Firstly, a variety of collaborative schemes based on fountain coding in binary delete relay channel are given, and the optimal scheme is obtained according to the performance. Then, the concept of asymptotically optimal fountain coding is used to extend this optimal scheme to wireless Following the channel, and using the queuing theory to achieve the optimal flow control of relay nodes, given the relay control flow of wireless relay channel cooperation program. The simulation results show that the relay channel cooperation scheme based on fountain coding can effectively solve the problem of relay buffer overflow and improve the channel reachable rate.
