Classification of MIMO Equalizers
Wing Chau Ng, Chuandong Li
In this theoretical work, the DSP-perceived channel in optical coherent communications is first simplified, based on which we categorize linear MIMO equalizers into four classes ac…

Transmitter IQ Skew Calibration using Direct Detection
Wing Chau Ng, Xuefeng Tang, Zhuhong Zhang
We propose a transmitter skew calibration based on direct detection of coherent signals with estimation errors of +/-0.2ps, providing a reliable, accurate and low-cost scheme to ca…
