研究了基于完全信道信息和部分信道信息的最佳中继选择策略认知中继网络中断概率,详细推导了这两种策略中断概率的封闭表达式,然后分析了它们的平均误码率.仿真结果表明,基于完全信道信息的中断概率和平均误码率性能要优于部分信道信息,并且两种策略的性能随中继节点数目、干扰温度增加而提高.

@@@@This paper investigates the outage performance and average error bit rate of cognitive relay network,in which the best relay is selected based on full and partial channel state information,respectively. The closed-form expressions on outage performance for both relay selection schemes are derived,and their average error bit rate performance is analyzed. Simulation results confirm the accuracy of the analytical results,and highlight per-formance gains provided by increasing the number of relay and interference temperature.
