Please answer it correctly thank you

Write a MATLAB program that performs simulation of a binary polar line code signal encoded as a differential encoded duobinary signal (duobinary with a precoder) with channel added Gaussian noise to the received signal, y(k T). You can generate a random input bit sequence with the MATLAB function randi and use the duobinary function provided earlier to generate b. Use a 10,000 length sequence y (kTs) = bk + v.-a, + ak-1 + Vk where vk is the channel added Gaussian noise You can use the MATLAB function awgn to add Gaussian noise to b at a specified signal to noise ratio, SNR. Measure the bit error rate (BER) (number of received bits in error as to ratio of the total bits) for three levels of channel noise, SNR = 1, 5, 10 dB, relative to the signal power. Plot the original sequence, the Duobinary differential encoded signal with and without noise and the received binary sequence for the first few samples. See Figures 1 and 2 below. Also plot the BER vs the SNR (not shown here). I assume the received pulse was a 0 if ly(k T) 21 and a if ly(k Tb). Publish your MATLAB code and results and upload to Blackboard.

For example, I got BER to be in the range [0.0001, 0.0016] over multiple runs with SNR-10
