  In this project, the behavior of Generalized Approximate Message-Passing
Decoder for BSC and Z Channel is studied using i.i.d matrices for constructing
the codewords. The performance of GAMP in AWGN Channel is already evaluated in
the previous scientific work of Jean Barbier, therefore, this project mainly
focuses on the performance of GAMP decoder for BSC and Z Channel. We evaluate
the performance of the GAMP decoder for sparse superposition codes at various
settings and compare the performance of decoder for different channels and
parameters.
