Abstract:
In this paper, an algorithm for implementing Interleave Division Multiple Access (IDMA) is introduced and also a permutation polynomial interleaver (PPI) is suggested as a user specific interleaver in IDMA .The proposed technique can solve the memory cost problem for chip level interleavers and reduce the amount of information exchange between mobile stations and base stations to specify the interleaver used as there identifications. We compare the proposed PPI with recent interleaver designs such as Random, Tree and Prime Interleaver. Performance analysis of IDMA with Binary phase shift keying (BPSK) modulation employing the proposed PPI in Additive White Gaussian Noise (AWGN) channel is carried out. In addition to that, we compare between interleavers from point of view complexity & bandwidth against number of user.
