ABSTRACT

In Digital Communication System, the requirement of high-speed data transmission achieved through the channel is most important. But in transmission, the data flow rate is reduced due to the Inter Symbol Interference (ISI). For removing this ISI, we require a Channel equalizer. In this paper, we used the Least Mean Square (LMS) equalizer technique. LMS technique shows the convergence of weights with sampling instant and also compare the eye diagram before and after the adaptive equalizer. The adaptive LMS equalizer reduced the ISI and gives better performance.
