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 for students of wireless communication.

The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.The discrete input is...

I'm actually having trouble with the equalization of the channel, because the doppler effect introduces phase rotation, which I don't know how to correct. If anyone could help me, I' d be really thankful.
