Least Mean Square (LMS) algorithm is used to minimize the mean square error (MSE) between the desired equalizer output and the actual equalizer output.
Step 1: Initialize the weights with values 𝒆_𝟎.
Step 2: With this value, compute an approximation for the gradient of the MSE.
Step3:
We next compute an updated estimate of the weight vector e by adjusting weights in the direction of the negative gradient.
Where 𝝁 is a user defined parameter that determines convergence and residual error.
