File Information

This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme.

MATLAB release MATLAB 7.0.4 (R14SP2)

I found a problem with this code.
When no noise is added and when the rxed_data is collected for every frame, then there is an error when compared to t_data

Well done! A few parts I feel could be done better (specifically the choice of using trellis and pilot insertion) but all in all quite straight forward and easily understood. Thanks!
