  1. Rake reception is used for improving the wide band receivers

    提高寬帶接收機性能,我們選擇,犁耙式接收。
  2. 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

    但是利用擴頻信號的自相關特性,可分辨多徑可以被有效分離,最優接收機等效為對多個具有獨立平坦衰落通道(或頻率非選擇性通道)特性的多徑信號進行最大比合併,即相干rake接收。
