Repeat Problem 10.32 and use the MMSE criterion for optimizing the tap coefficients. Assume that the noise power spectrum is 0.1 W/Hz.
Problem 10.32
Determine the tap weight coefficients of a three-tap zero-forcing equalizer if the ISI spans three symbols and is characterized by the values x (0) = 1, x ( -1) = 0.3, and x (1) = 0.2. Also, determine the residual ISI at the output of the equalizer for the optimum tap coefficients.
