    testing ofdm system for varying dopler frequency

    rayleighchan.m dear friends.. did anybody used the function by name : rayleighchan in matlab.. actually when i use this function for simulating my ofdm system by making dopler frequency = 0 ..is working well..but when i make dopler frequncy Fd is varying the code is not giving any performance...
