1. Margulis.m was used to extract H matrix from Alist
2.The code are forAWGN/ BSC/BEC channel for log-domain as
well as for Min-sum decoder.
2.1 Load Margulis.mat (N=2***0 code) in workspace to simulate. Enter the iteration 100000 for hamming code and 1000 for N=2***0 length code.
2.2 Depending upon whether to run coded or uncoded transmission or whether to run Hamming code or Margulis(N=2***0) , remove the comments,
2.3 Simulation took 1.5 to 2hr to show the output
