线性网络编码中继协作通信的分集复用折衷

Diversity-Multiplexing Tradeoff of Cooperative Communication with Linear Network Coded Relays

Hakan Topakkaya, Zhengdao Wang

摘要:

为了减轻无线传输中衰落带来的不利影响,同时获得高吞吐量和更好的频谱效率,网络编码和协作通信受到了研究界的广泛关注。在这项工作中,我们分析了网络编码方案的合作通信设置与多个源和目的地。该协议实现了充分的多样性秩序在一个稍微减少的复用率相比,现有的计划在文献中的代价。我们表明,我们的计划优于传统的合作方面的多样性复用的权衡。

英文摘要:

Network coding and cooperative communication have received considerable attention from the research community recently in order to mitigate the adverse effects of fading in wireless transmissions and at the same time to achieve high throughput and better spectral efficiency. In this work, we analyze a network coding scheme for a cooperative communication setup with multiple sources and destinations. The proposed protocol achieves the full diversity order at the expense of a slightly reduced multiplexing rate compared to existing schemes in the literature. We show that our scheme outperforms conventional cooperation in terms of the diversity-multiplexing tradeoff.
