MC-CDMA

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

MC-CDMA

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

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

I am now working on it. but i think the time delay due to the interleave operation may be a problem in CR scenario. since the spectrum hole may be only available in a very short time
