摘要

轨道角动量模分复用(OAM-MDM)通信在水声通信领域具有提高数据传输速率和降低信号处理复杂度的巨大潜力。但是，OAM信号受到多径的影响，导致数据流无法分离。此外，换能器的不一致性会破坏OAM模式的纯度，降低水声OAM- mdm的有效自由度。在此，我们推导了OAM信号的波前，分析了理想条件下的水声OAM- mdm。利用决策反馈均衡器(decision-feedback equalizer, DFE)来缓解水声OAM-MDM系统中换能器的多径和不一致性造成的模间干扰。仿真和实验验证了理论分析的正确性。

Equalization in Underwater Acoustic Orbital Angular Momentum Mode-Division Multiplexing

Orbital angular momentum mode-division multiplexing (OAM-MDM) communication has great potential to increase the data transmission rate and reduce the signal processing complexity in the field of underwater acoustic communications. However, the OAM signals suffer from the influence of multipath leading to the data streams unable to be separated. In addition, the inconsistency of transducers will destruct the OAM mode purity, and decrease the effective degree of freedom of underwater acoustic OAM-MDM. Here, we derive the wavefront of the OAM signals to analyze the underwater acoustic OAM-MDM under ideal conditions. The decision-feedback equalizer (DFE) is exploited to mitigate the multipath and the inconsistency of transducers causing inter-mode interference of the underwater acoustic OAM-MDM. The theoretical analysis is verified by both simulations and experiments.
