The interchannel interference(ICI) and the residual intersymbol interference(ISI) could be introduced by time varying channel with channel impulse response that exceeds the length of CP.
时变信道以及信道冲激响应超过CP会带来子信道间干扰(ICI)和残留码间干扰(ISI),产生误码率平台。
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。
Decision feedback equalizer (DFE) is an efficient and low-cost scheme for suppressing intersymbol interference (isi) in vestigial sideband (VSB) based digital TV (DTV) receivers.
对于减少基于残留边带调制(VSB)的数字电视(DTV)接收机的符号间干扰(ISI),判决反馈均衡器(DFE)是一种简单而有效的方案。
