In this paper, an efficient coordinate descent method (CDM)-based turbo-type iterative detection algorithm is proposed for uplink interleave division multiple access (IDMA) systems. The simulation results and analysis reveal that the proposed CDM-based detector provides improved bit error rate (BER) performance compared to the conventional elementary signal estimator (ESE) conceived for IDMA systems. Meanwhile, by taking into account both the convergence performance and the computational complexity, we show that the proposed CDM-based detector is also superior to conventional ESE.
