摘要:

提出了一种多入多出交织分多址(MIMO-IDMA)系统的迭代多用户检测架构。通过不同的码片级交织序列识别用户,检测器采用新颖的基于均值的软判决多用户检测(SoD)算法。仿真表明,所提出的基于IDMA的SoD检测算法比传统MMSE线性检测算法性能改善约2 dB,优于SoIC算法约1 dB,有较低的误码率和复杂度。

Abstract:

An iterative multi-user detection receiver structure is proposed for multiple input multiple output interleave division multiple access (MIMO-IDMA) systems. Different chip-level interleaving signatures distinguish users. A novel mean-based soft decision multi-user detection (SoD) algorithm is applied in multi-user detector. Simulation results show that the proposed SoD detection scheme improves the performance in SNR around 2dB compared to MMSE, 1dB superior to SoIC, and has lower bit error rate and complexity.

Key words: multiple input multiple output ;interleave division multiple access, iterative multi-user detection
