Abstract

Previously, the interleavers is generated randomly for users of Interleave Division Multiple Access (IDMA) systems. Therefore, transmitting the entire chip-level interleaver matrix or power interleaver generation is required, which either adds redundancy or increases delay. In this paper, we propose to use deterministic chip-level interleavers for multiple users of IDMA systems. These chip-level interleavers are modified from single-user symbol-level interleavers for turbo codes. The receiver can generate the chip-level interleavers for user k automatically without the redundancy of transmitting the entire interleaver matrix or the delay of generating power interleavers. Simulation results show that the proposed deterministic–interleaver-based IDMA performance is better than Gold-code-based CDMA in the multipath environment.
