摘要

考虑了双向半双工中继信道的可实现速率。该信道模型适用于星型拓扑的无线网络,其特点是由于节点之间没有可靠的直接链路,网络中的所有流量都要经过中继。编码和多址策略在中继端利用网络编码,在接收机端利用模拟转发消除干扰。给出了离散无记忆网络的可实现速率区域,并对加性高斯白网络进行了扩展

Two-Way Radio Networks with a Star Topology
Achievable rates for two-way half-duplex relay channels are considered. This channel model is applicable to wireless networks with a star topology characterized by a traffic model where all traffic in the network traverses the relay due to the lack of a reliable direct link between the nodes. The coding and multiple-access strategies make use of network coding at the relay in addition to analog forwarding with interference cancellation at the receivers. An achievable rate region for discrete-memoryless networks is given as well as extensions for the additive white Gaussian network
