自适应信道缩短方法实现信道均衡

In multicarrier modulation systems (MCMs), there are intersymbol interference and interchannel interference.,blind adaptive equalizers are used to the channel for combating these problems.A time-domain equalizer (TEQ) placed in cascade with the channel produces an effctive impulse response that is shorter than the channel impulse response.This paper analyzes two TEQ design methods:sum –squared auto-correlation minimization and single lag autocorrelation minimization.These two methods succeed in shortening the channel and combating the problems above,and achieve the better bitrate.
