hello, I am currently studying wireless communication and I am facing a problem in my MIMO OFDM simulation using mimochan function.
My problem is mainly that my input signal is not time based and therefore, whatever sampling time I use in the function the SNR vs BER is always the same. I would like to investigate the Cyclic prefix effect by varying the length of that one but in my simulation, whatever the length of it (1/4, 1/8, 1/16, 1/32), the obtained results are same.
If anyone has code or can point me to a tutorial where I will be able to find example of this function for MIMO OFDM system, it would be great.
