摘　　要：基于均方误差(MSE)准则,分析线性均衡器在补偿有符号间串扰(ISI)信道中的码间干扰时的性能状况.论文分别在不同离散时间信道下和同一离散时间信道但却不同的抽头下分析线性均衡器均衡效果.理论与仿真结果均显示:线性均衡器能大大降低符号间串扰,达到补偿ISI的目的.并且抽头数越多均衡效果越好,但当抽头数达到一定值时,均衡效果的进一步改善不大.The performance in which the channel with ISI is compensated by equalization approaches is analyzed. Two cases are analyzed：one is in different discrete -time channels, and the other is in the same channel but having different taps. Results of the analysis and emulation show that the linear equalizer can reduce the ISI greatly, and the channel with ISI can get good compensation. As the number of equalization taps increases, the equalization quality is on a rise, but it will not increase any more when the number of taps is large enough.
