In this paper, we review the nondata-aided constant-modulus algorithm (CMA) and a data-aided decision-directed algorithm (DDA) for polarization control and propose different extensions to both algorithms to improve their performance. The first extension to the CMA enables a common carrier recovery (CCR) through differential phase compensation (DPC-CMA). The second extension adapts the CMA for quadrature amplitude modulation signals (CMA-QAM). Both extensions can be combined to form a DPC-CMA… CONTINUE READING
