摘要：

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.
