多径效应的时域表示实际上就是不同路径来的信号存在随机的时延差。对于抗其它扩频信号干扰性能，及抗多址干扰性能。我们这里考虑简单的情况，只考虑一个用户干扰的情况，说明其具有抗多址干扰性能就行。(Multipath effect is actually a time domain representation of the signal path to the existence of different random time delay difference. Other spread spectrum signal for the anti-interference performance, and anti-MAI performance. Here we consider the simplest case, considering only one user interference, indicating its performance with anti-multiple access interference on the line.)
