matlab program for calculating to find bit error rate

Consider the ISI channel given by the impulse response in Problem 3.18. Plot a BER vs Eb/No curve for this channel without using any equalizer with antipodal signaling. Next, design a 3-tap zero-forcing equalizer and use this equalizer for this channel to simulate and plot the BER vs Eb/No curve. Finally, design a 5-tap equalizer and repeat the experiment to plot another BER vs Eb/No curve. All your results should be presented in one figure that shows three simulation curves: no equalizer, 3-tap equalizer and 5-tap equalizer, each distinguished with appropriate legend. You must provide the equalizer taps obtained from your design for each case and (as always) the codes must be attached. The error probability (demonstrated in the figure) should be approximately in the range of 0.1 to 10^(-6)
