The orthogonality, however, is impaired by multipath fading channels, thus causing multicode interference (MCI) and deteriorating the system's performance at high data transmission rates.
但是这种正交性却被多径衰落信道破坏，产生了多码道干扰，严重影响了系统高速传输数据的性能。
It can waken the multipath effect availably, eliminate symbol interference and fight against frequency select fading. Moreover, the channel utilization rate is high.
他能有效地对抗多径效应，消除符号间干扰，对抗频率选择性衰落，而且信道利用率高。
In shortwave communication system, Intersymbol Interference is serious and signal is distorted extremely because of fading channel resulted in by the effect of multipath.
在短波通信系统中，由于多径效应常常引起信道衰落，直接结果是码间串扰非常严重。
