Question: [Sum-Product Decoder] Write a MATLAB script to implement the sum-product decoding algorithm for a linear block code with parity check matrix H when BPSK modulation is used over an AWGN. The inputs to the script are H, channel output sequence y, maximum number of iterations, symbol energy E, and Eb/ No in dB. Apply the script for decoding a (7,4) Hamming code at different values of Eb/ No when the all-zero sequence is transmitted. For convenience assume E = 1.
