Abstract:

Because of the multipath effect,intersymbol interference (ISI)is inescapable during data transferring process in wireless data communication system. In order to compensate the non-ideal characteristic of channel and reduce signal distortion and error-coding probability of communication system,equalizer has to be used in the receiver.Cause adaptive equalization can track the channel environment and antomatically adjust coefficient,it has become a critical technique in communication system. Adaptive equalizer investigates and implements is based on LMS algorithmon FPGA hardware platformwith verilog programming language.
