Recently some new multiple access schemes attracted much attention. Namely OFDM-CDMA and IDMA. So, this paper outlines the basic principals of OFDM-CDMA and IDMA. A comparative study of OFDM-CDMA and IDMA is given here on the basis of some attractive features like low-cost iterative multi-user...

Now-a-days, a new multiple access scheme called interleave-division multiple access (IDMA) has attracted much attention, in which interleavers are used as the only means for user separation. It has been shown that the IDMA can achieve near single user performance in multi-user environment with...

This paper outlines a survey on interleave-division multiple-access (IDMA) technique which exploits the interleaving as only means of user separation instead of by different signatures as in a conventional code-division multiple-access (CDMA) scheme. IDMA scheme can achieve near single user...
