摘要

摘要: 现有协作组播网性能分析仅考虑噪声受限系统，忽视了干扰对系统的影响.对多蜂窝小区环境下协作组播网的性能进行分析，协作组播网中，中继和目的节点同时受到多个蜂窝小区的共道干扰.共道干扰的考虑造成目的节点接收端信干噪比间存在相关性.考虑到该相关性，推导出系统中断概率和遍历容量精确表达式，在此基础上研究其分集和编码增益.仿真验证了理论推导的有效性.

Abstract: Most of the previous works on performance analysis of multicast relay networks (MRNs) have focused on noise-limited environments, where the effect of interference on MRNs has been ignored. In this paper, we investigate the performance of MRNs in a multicell environment. It is shown that the received signal to interference plus noise rations (SINRs) at the destinations are correlated due to the cochannel interference from the others. Considering the correlation, the exact outage probability and ergodic capacity are derived, based on which the diversity and coding gains are obtained. The analytical results are validated by simulations.
