摘要:

本文讨论和研究了高频谱效率的双向四节点无线网络中继协作策略。其系统模型为线型放置的4个节点要通过中间2个节点的协作来实现两组数据的交换,系统中的4个节点均采用单天线半双工传输方式,整个传输周期由4个时隙构成。基于该系统模型,本文给出了3种不同的实现策略,并对它们可获得的速率范围进行了分析。

Abstract:

Bi-directional relaying strategies for linear four-node wireless network are discussed in this paper. The system model is that linear four nodes want to realize the bi-directional information exchanges of two packets that are belong to two pairs of nodes respectively. Each node is equipped with single antenna,and operates in half-duplex model,and a transmission period consists of four slots. For this cooperative bi-directional relaying model,three relaying strategies are proposed as well as the analysis of achievable rate region.

Key words: wireless communication, superposition coding, network coding, cooperative, cognitive receiver
