relay receiver

The novel cooperative communication scenario takes both the direct link and relay link of secondary user into consideration for data transmission. Then the receiver of secondary user merges the signals from the two links to obtain diversity gain and improve system performance.

新的协作通信场景是指同时利用次级用户的直接链路和中继链路来协同传输数据，次级用户的接收端通过对两条链路的信号进行合并处理，从而获得分集增益，提升系统的性能。

Secondly, this paper does research on the performance of Relay access link receiver, and simulates and obtains the key performance indicator of the receiver such as reference sensitivity and dynamic range.

其次，对Relay access link接收机性能进行了研究，通过仿真获得了其参考灵敏度、阻塞特性、动态范围等接收机性能指标。
