secondary relay

An integrated-circuit transformer differential relay including secondary and fifth harmonics suppressor is designed.

设计了一种集成电路 型 具有二次五次谐波制动的变压器差动继电器.

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。
