Amplifier distortion produces a dilation of the spectrum of the input signal (" spectral regrowth ") which causes interference to communications in adjacent channels.

放大器失真引起输入信号的频谱再生，这对相邻信道中的通信产生了干扰。

Time variant multipath propagation in acoustic channel causes serious intersymbol interference (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。

Timing offset causes inter-symbol interference, and frequency offset would destroy the orthogonality between subcarriers, causing ICI, which lead to a sharp decline in overall system performance.

定时偏差会导致码间干扰，频率偏差会破坏子载波间的正交性，引起子载波间干扰，从而使系统整体性能急剧下降。
