The interchannel interference(ICI) and the residual intersymbolinterference(ISI) could be introduced by time varying channel with channel impulse response that exceeds the length of CP.
Compared with traditional decoding method, simulation results of the new scheme show evident improvement in overcoming the severe intersymbolinterference (ISI) of GMSK signals.
Time variant multipath propagation in acoustic channel causes serious intersymbolinterference (ISI), which makes high speed data transmission over acoustic channel very difficult.
但水声信道的时变多途效应造成接收数据严重的码间干扰（ I S I），使得高速水声通讯的实现十分困难。
