针对无线网络中用户到协作节点和目的节点的上行链路不可靠的问题
研究了协作通信系统中具有特定协作节点的协作方案.在用户到协作节点的上行链路不可靠的情况下
将信道编码、网络编码同时引入到协作通信系统而建立了基于联合信道-网络编码的协作通信机制
并推导出系统中断概率的表达式; 以中断概率作为系统性能的衡量标准
研究了能量分配、码率分配对系统性能的影响
给出了合适的分配方法.仿真实验表明
即使用户到协作节点的上行链路不可靠
所提协作机制也能获得空间分集
从而提高了网络的性能.
A cooperating mechanism with dedicated cooperating nodes is studied to solve the unreliability problem of up links from users to cooperating nodes and destinations in wireless communication system. In the case that up links from users to cooperative nodes are not reliable
both channel coding and network coding are introduced into the cooperative communication system to propose a cooperating mechanism based on joint channel-network coding. As a measure of system performance
the system outage probability is analyzed and an expression for the probability is derived. Effects of energy allocation and rate allocation on the system performance are analyzed based on the system outage probability
and then an appropriate allocation method is proposed. Analysis and simulation show that even though up links are not reliable
the proposed cooperating mechanism can still achieve spatial diversity
and improve the system performance.
