Non-Data-Aided Wide-Range Frequency Offset Estimator for QAM Optical Coherent Receivers
Non-Data-Aided Wide-Range Frequency Offset Estimator QAM Optical Coherent Receivers
2015/5/20
We propose and experimentally demonstrate a novel blind frequency offset estimator for coherent quadrature amplitude modulation (QAM) receivers. Its frequency offset estimation range is more than thre...
