摘　　要：自适应均衡器已广泛应用于通信、雷达、声纳、控制和生物医学工程等许多领域,为克服多径衰落和信道失真引起的码间干扰,实时跟踪移动通信信道的时变特性,笔者设计了一个基于LMS算法的自适应线性均衡器,并通过改变步长因子Δ来分析其收敛速度和均方误差特性.As an important aspect of adaptive signal processing,adaptive equalization is widely used in the field of telecommunication,radar,sonar,control and bio medical engineering.In order to overcome the intersymbol interference caused by multipath fadiy and channel distortion,and according to the time-dependent charateristics of real-time tracking mobile communication channel,the author designs on adaptive linear equalization based on LMS algorithm and analyzes its convergence rate and mean square error characteristics by varying the step factor.
