Abstract

In this paper, we propose a time reversal (TR) based time division duplex (TDD) interleave-division multiple access (IDMA) scheme (TDR-IDMA). Multiple user interference (MUI) can be greatly suppressed with TR technique. The Turbo-type iterative detection can achieve fast convergence speed with a little additional complexity at base station. From simulation results, we found that only five iterative processing can achieve acceptable performance for a length-16 repetition code. The single-path, multi-path and complex channel models are discussed in this paper.
