Description

This item was taken from the IEEE Conference ' Novel FIR-filter configuration tolerant to fast phase fluctuations in digital coherent receivers for higher-order QAM signals ' We propose a novel configuration of FIR filters adapted by the decision-directed LMS algorithm in the digital coherent receiver. Simulations and experiments show its high tolerance to phase noise and frequency offset for 16-QAM signals.
