to have MC CDMA, first spread and then do OFDM
I'm also working on it, but I'm not too good at ZF equalization and combining techniques
Montadar, some time ago I had requested a paper, try to find that paper, since it will help us all

Montadar, it is the one for which I was warned too, I wonder if they would again warn me
BER comparison of DS-CDMA and MC-CDMA for frequency selective fading channels by Ramjee Prasad
See if you can find it, then send it to me.
Apart from it try Kaiser's book on MC and Spread Spectrum communication systems

| well this is it. You can also go through the paper of "Overview of MC-CDMA" by Ramjee Prasad, I can send it to you if you dont have it

Here you go.
Do you have good explanatory simulations for MC-CDMA combining techniques?

i stopped since last time because the approval of my government was very late. just now i get the approval and i must start again now. so that i must prepare another proposal work for my second try for the PhD, can you help me?
thanks for your interest.

Sure brother. May I suggest you work on Interleave Division Multiple Access for PhD. Something like MC-IDMA with scheduling? or Spectrum sharing algorithms used in Cognitive Radio
Maybe these are generic topics for PhD but these are going to be hot topics if not already
