Repeat Problem 9.41 using the MSE as the criterion for optimizing the tap coefficients. Assume that the noise power spectral density is 0.1 W/Hz.
Binary PAM is used to transmit information over an unequalized linear filter channel. When a = 1 is transmitted, the noise-free output of the demodulator is
a. Design a three-tap zero-forcing linear equalizer so that the output is
b. Determine qm for m = ±2, ±3, by convolving the impulse response of the equalizer with the channel response.
