title = "Modified constant modulus algorithm based on constellation matching error with variable weight",
abstract = "In this paper, we propose a modified constant modulus algorithm based on constellation matching error with variable weight (VW-CME-MCMA) for polarization-mode dispersion (PMD) equalization in coherent optical communication system. The new algorithm added a constellation matching error (CME) term to the cost function of the traditional modified constant modulus algorithm (MCMA), considering that the CME term does not provide correct error information in the early stage of algorithmic equalization. In this case, the CME is equivalent to the noise role. Therefore, the new algorithm adaptively adjusts the weight of the CME term according to the error value of the current equalizer output signal. Through the analysis of simulation results, the new algorithm proposed in this paper can achieve faster convergence speed and lower steady-state error.",
