(BICM) using a (7,4) Hamming code and M-PSK.

hello. Does anyone who have worked in BICM already can help? I almost finished it but i got stuck in receiver part.

1. Transmitter including encoder, interleaver and modulator. 2. AWGN Channel. 3. Receiver including iterative decoder and demodulator. consider the following cases in simulation: 1. Effect of the packet size by varying it from 100, 500, 1000 coded bits. 2. Effect of the constellation size, M = 4, 8 and 16. 3. Effect of the number of iterations: 1, 2, 3, 5.
