瑞克接收法
Examples
- Rake reception is used for improving the wide band receivers
提高宽带接收机性能，我们选择，犁耙式接收。 - However , multipath components can be resolvable due to the autocorrelation of the spread spectrum signal , thus the optimal receiver equals coherent rake reception , i . e . maximum ratio combining the independent components which endure flat fading or frequency non - selective fading . synchronization of pn code and separation of resolvable multipath components need to estimate the exact time delay among the multipath components
但是利用扩频信号的自相关特性，可分辨多径可以被有效分离，最优接收机等效为对多个具有独立平坦衰落信道（或频率非选择性信道）特性的多径信号进行最大比合并，即相干rake接收。
