Digital signal processing algorithms for optical communications

We design a cascaded filter with three stages in a 25-GBaud 256-QAM optical fiber transmission system. The experiment results show a 15.12% reduction in computational complexity and a 0.53-dB SNR improvement compared to conventional LMS+PLL.
