信道的频率响应是时变的，设计最佳的固定的解调滤波是不可能的，因此，需要一种能补偿或减少接收信号中ISI的方法，这种ISI补偿方法称为均衡方法。
自适应均衡技术能够用来抵消由于信道带限或时间色散所导致的码间干扰，可以使通信系统更有效地利用信道带宽。
(Channel frequency response is time-varying, the best fixed design demodulation filter is impossible, therefore, need to be able to receive compensation or reduce the signal in the ISI method, the ISI compensation is called a balanced approach. Adaptive equalization techniques can be used to offset the channel band-limited or time dispersion caused by the inter-symbol interference can make communication systems more efficient use of channel bandwidth.)
