摘要

非正交多址(NOMA)方案是提高无线网络频谱效率的可行方案。在本文中，我们改进了交错多址(IDMA)和低密度扩展码分多址(LDS-CDMA)技术用于非相干光通信，如可见光通信(VLC)系统，并比较了它们的性能。仿真结果表明，光IDMA在误码率方面优于光LDS-CDMA。

Performance Comparison of OIDMA and Optical LDS-CDMA

Non-orthogonal multiple-access (NOMA) schemes are viable solutions to enhance the spectral efficiency of wire-less networks. In this paper, we modify the interleave-division multiple-access (IDMA) and low-density spreading code-division multiple-access (LDS-CDMA) techniques for use in non-coherent optical communications, such as visible light communications (VLC) systems, and compare their performance. Simulation results show that optical IDMA outperforms optical LDS-CDMA in terms of bit-error rate (BER).
