摘　　要：针对光纤偏振复用两束偏振态相互正交的光在一根光纤中传输时,由于偏振模色散(PMD)、偏振相关损耗(PDL)等原因对接收到的偏振复用信号造成干扰的问题,提出了基于负熵最大化的不动点复数ICA算法,并用此算法对接收到的信号进行解复用。结果表明,采用ICA算法后,在冶金自动化控制系统通信中,光信噪比很大的情况下也能保证很低的误码率,满足传输质量要求。To address the problem of interference of received polarization multiplexed signals due to polarization mode dispersion(PMD) and polarization correlation loss(PDL) when two beams of light with mutually orthogonal polarization states are transmitted in a single fiber, an immobile point multiplexed ICA algorithm based on negative entropy maximization is proposed, and the received signals are demultiplexed using this algorithm. The results show that with the ICA algorithm, a very low BER can be guaranteed to meet the transmission quality requirements in the metallurgical automation control system communication with a large optical signal-to-noise ratio.
