A prime pair based interleaver design for IDMA systems

Interleave Division Multiple Access (IDMA) is a novel approach for multiple access communications. In the IDMA systems, interleavers are the only means of user separation. Thus, the interleavers must be carefully designed. Good interleavers should meet three criteria including low memory requirement, easy generation and low correlation among interleavers. Although there are several existing interleavers which meet some of these criteria, the interleaver design efficiency still can be improved. In this paper, a prime pair based interleaver design is proposed to generate a suitable set of interleavers. The simulation results show that the prime pair based interleavers perform as well as the random interleavers and reduce the memory cost and complexity.
