Orbital angular momentum (OAM) beams have orthogonality between them, which can greatly increase the capacity of a communication system, but an OAM multiplexed communication system will be affected by atmospheric turbulence during transmission, which will cause channel crosstalks. In this paper, we adopt the blind equalization algorithm, which can recover multiple signals with blinding source separation, to equalize a communication system. The reduction of average bit error rate and the convergence of constellation demonstrate the effectiveness of the proposed algorithm in suppressing channel crosstalks.

用MCMA-MUK算法抑制轨道角动量复用通信系统中的串扰

轨道角动量（OAM）波束之间具有正交性，可以大大增加通信系统的容量，但OAM复用通信系统在传输过程中会受到大气湍流的影响，从而引起信道串扰。在本文中，我们采用盲均衡算法来均衡一个通信系统，该算法可以恢复多个盲源分离的信号。平均误码率的降低和星座的收敛证明了该算法在抑制信道串扰方面的有效性。
