The demonstration of n-PSK modulation and demodulation with my own speech, with different value of n and sampling frequency and carrier, n = 2, 4, 8, 16 ,32...
This program constitutes of very basic amplitude modulation and demodulation implementation for beginners. Comments have been made.
this model provides a dsb sc modulation and demodulation using a real input i.e.any audio signal.
These files just to simulate or demo M-QAM modem in case BER, channel model, signals in t and f domain.Overal proses from bit insertion at modulator to bit estimated in demodulator. We can see the change of signal in each block diagram.
Basic familiarization about AM and FM, i have taken my speech to check whether AM or FM properly recover the signal or not, after modulation and demodulation.
This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful...

theoretical and simulated BER are in good agreement in AWGN channel the result can be extended to general M-QAM using slight modification .
A stack-based sequential depth-first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the...
