There is no simple matlab code to mimic the MC-CDMA system because you would have to specify several things such as fading (e.g. Rayleigh or Rician) etc.
Read this paper: R.Prasad and S. Hara, “An overview of Multicarrier CDMA”, Proc. of IEEE ISSSTA ’96, Mainz, Germany, Sept. 1996, pp. 107-14.
Im doing a Final Year Project on the Peak-to-Average Power Reduction techniques in a MC-CDMA systems. First of all, I'll have to have a basic MC-CDMA system with AWGN as the channel.
Currently I have the code for OFDM spectrum generation which I obtained from MathWorks website. I plan to use the code as the OFDM modulation and demodulation part of the whole MC-CDMA system.
By using the code, I managed to generate an OFDM spectrum and i tried to compute the BER. However, the total number of signals after FFT doubles the input signal which caused the BER computation fails.
Do you know why does this happen and how to solve this problem?
Thank you.
P/S: The code which I'd obtained can be accessed through this link **broken link removed**
