  • Abstract
    An uncoded IDMA system with chip accumulation for partial users is proposed. The rate-1 accumulators are employed for partial users. Simulation gives an optimal number Ks of partial users for K-user uncoded IDMA system with the lowest BER. Simulation results show that the performance of the proposed system is improved, compared with the conventional IDMA system, especially for few users and in high Eb/N0 levels.
