摘要
协同通信是一种可通过各节点的分布式天线获得类似MIMO系统分集和复用增益的有效技术,而放大转发协议通过协同节点直接把接收到的源信号放大转发给目的节点,实施简单且高效。针对基于放大转发协议的协同通信系统,建立了半双工的时分系统模型,分析了放大系数的范围,并在此基础上推导了采用放大转发协议的协同通信系统最大传输速率。
Cooperative communication is an efficient technology to obtain similar diversity and multiplexing gains of MIMO system through distributed antennas of different nodes.In amplify-andforward protocol the cooperative node directly amplifies and forwards the received signal from source node to destination node,which made the protocol efficient and easy to implement.This paper,for cooperative communication systems based on amplify-and-forward protocol,founds half-duplex time division system model,analyze the bound of amplifying coefficient,and inferential reasoning the maximum transmission rate for cooperative communication system based on amplify-and-forward protocol.
