摘要

针对多输入多输出（MIMO）检测算法在大规模模式数目的模分复用（MDM）光纤信道中用来补偿模式相关损耗（MDL）时，会出现计算复杂度过高、性能下降的问题，文章提出将大规模MIMO检测算法应用于光纤信道中。文章研究的算法有最小均方误差（MMSE）、共轭梯度（CG）、高斯-塞德尔（GS）、基于无穷范数的乘子交替方向（ADMIN）法和基于盒约束的优化坐标下降（OCDBOX）法。结果表明，在MDL受损的光通信系统中，OCDBOX算法表现出最好的误码率（BER）性能，但复杂度较高。而ADMIN检测算法具有次好的BER性能和较低的计算复杂度，因此在MDL受损的MDM系统中，ADMIN检测算法可以作为良好的候选方案。

Abstract

Multiple Input Multiple Output (MIMO) detection algorithm is used to compensate the Mode Dependent Loss (MDL) in Mode Division Multiplexing (MDM) optical fiber channel. The problem of MIMO detection algorithm is that the computational complexity is too high and the performance is degraded with a large number of modes. This paper proposes to apply Massive-MIMO detection algorithms to the fiber channel

The algorithms include Minimum Mean Square Error (MMSE)

Conjugate Gradient (CG)

Gauss Seidel (GS)

and Alternating Direction Method of multipliers based Infinity-Norm (ADMIN)

and Optimized Coordinate Descent based BOX constraint (OCDBOX) . The result shows that the OCDBOX has the best Bit Error Rate (BER) performance in MDL-impaired MDM optical fiber communication system while higher complexity. The ADMIN has the second best BER performance and lower computational complexity. Therefore

the ADMIN detection algorithm can represent a good candidate in the MDM system with MDL.
