On Interleaver Design for Interleave Division Multiple Access (IDMA)

Interleave Division Multiple Access (IDMA) is a recently proposed technique for multiple access communications. With IDMA, interleavers are the only means of user separation. Thus, the interleavers must be carefully designed to ensure good performance, low memory requirements and low computational complexity. Although there are several existing designs which meet some of these criteria, the interleaver design efficiency still can be improved. In this paper, a new low complexity technique is proposed to generate a suitable set of interleavers.
