  This paper deals with the implementation of Least Mean Square (LMS) algorithm
in Decision Feedback Equalizer (DFE) for removal of Inter Symbol Interference
(ISI) at the receiver. The channel disrupts the transmitted signal by spreading
it in time. Although, the LMS algorithm is robust and reliable, it is slow in
convergence. In order to increase the speed of convergence, modifications have
been made in the algorithm where the weights get updated depending on the
severity of disturbance.
