In the digital coherent optical receiver, we can achieve polarization demultiplexing in the digital domain, using a two-by-two matrix controlled by the constant-modulus algorithm (CMA). In this paper, after elucidating the physics behind CMA for polarization demultiplexing, we discuss the performance limit of CMA-based polarization demultiplexing through computer simulations. The method of improving its performance is also demonstrated.
在数字相干光接收机中，我们可以利用由恒模算法（CMA）控制的二乘二矩阵在数字域实现偏振解复用。在本文中，在阐明用于偏振解复用的CMA背后的物理原理之后，我们通过计算机模拟讨论了基于CMA的偏振解复用的性能极限。还展示了提高其性能的方法。
