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

| Abstract: |
| 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, res
pectively. The closedform expressions on outage performance for both relay sel
ection schemes are derived, and their average error bit rate performance is anal
yzed. Simulation results confirm the accuracy of the analytical result
s, and highlight performance gains provided by increasing the number of relay an
d interference temperature. |
