Abstract :
Based on factor graph representation of IDMA (interleave division multiple-access) systems, an interleaver design criterion is proposed. The progressive edge growth (PEG) algorithm proposed for LDPC codes is adapted to multi-user interleavers pattern design. Simulation results show that the designed interleavers perform over random interleavers especially when the number of users is relative large.
