| 摘 要： | 对于广播和中继共存的协作感知场景，在存在信道估计误差的情况下，分析了基于放大转发方式感知数据上报时的误码率性能. 通过推导汇聚节点的有效信号噪声比，得出平均误码率的近似表达式. 实验结果表明，理论分析结果与仿真结果一致.

| Abstract: | The hybrid transmission scene involving both broadcasting link and relay link is considerd with channel estimation error.The bit error rate performance of amplify-and-forward based transmission in reporting sensing data is analyzed.By deriving effective signal to noise ratio at the common receiver,the approximate expressions for average bit error rate is obtained.Simulations are further provided to confirm the analytical results. |

| Keywords: | cognitive radio cooperative diversity amplify-and-forward relay channel estimation error |
