【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]:The performance analysis of existing cooperative broadcast networks only considers the noise limited system and neglects the influence of interference on the system. The performance of cooperative group broadcasting network in multi-cellular cell environment is analyzed, and the performance of cooperative group broadcasting network is analyzed. The relay and destination nodes are simultaneously affected by the co-channel interference of a plurality of cellular cells. The consideration of the co-channel interference results in a correlation between the signal-to-noise ratio at the receiving end of the destination node. The exact expressions of outage probability and ergodic capacity of the system are derived, and the diversity and coding gain of the system are studied, and the validity of the theoretical derivation is verified by simulation.
