| 摘 要： | 研究表明,协作中继选择能提高无线中继网络的鲁棒性和能效。文中研究一个多接入中继信道,包含2个信源,N个中继和1个信宿。中继节点为半双工,对两个信源的信号采用非再生的网络编码。考虑直接链路,基于最佳最差信道、最佳信噪比和最佳调和平均选择,提出新的选择策略。仿真结果表明其在性能上优于原有策略。

| Abstract: | It has been shown that cooperative relay selection schemes promise gains in robustness and energy-efficiency in wireless relaying networks.This paper considers multi-access relay channel(MARC) with 2 sources,N relays and 1 destination,where the half-duplexing relays perform non-regenerative network coding for the received signals from the two sources.Taking the direct links into consideration,it develops new single relay selection schemes based on best worst channel selection scheme,best signal-to-noise ratio selection scheme and best harmonic mean selection.The simulation results show that they outperform the existing schemes. |
