Description
Summary:Interleaver is very important to interleave-division multiple-access (IDMA) system for separating users. But most interleavers are designed for conventional IDMA detection. In this paper, an improved interleaver in downlink is proposed for orthogonal frequency division multiplexing interleave-division multiple-access (OFDM-IDMA) system in high speed circumstance. Simulation results show that compared with the conventional IDMA system, it can get time diversity gain and perform better.
