Design and Researeh of LMS Algorithm-Based Adaptive Equalizer with FPGA

In recent years,the technology of adaptive equalizer has been used largely in the communication systems. Using adaptive equalization in multi-path fading situation can effectively improve the receiver performance.In this paper the conception method of an adaptive equalizer by using LMS algorithm with FPGA on the basis of MATLAB simulation is described,the key function modules used in this adaptive equalizer are introduced in brief.The relative hardware platform employed with the adaptive equalizer devoloped in terms of the concept is expected to achieve certain design effect.
