Abstract :
In this paper, we propose a parallel interleaver design for interleave-division multiple-access (IDMA) systems. The advantages of our approach are the low complexity induced from an algebraic solution and the parallel processing with negligible performance degradations against random interleavers. It is specially suitable for parallel implementation of multiple user detections and decoding of IDMA signals, resulting in efficient improvements of system throughput. Simulation results show that the parallel interleavers perform as well as the random interleavers in an IDMA system.
