Abstract

See full text

A simplified coherent receiver based on heterodyne detection with only two balanced photo detectors (PD) and two analog-to-digital converters (ADC) is disclosed. The polarization diversity hybrid can be simplified relative to the conventional one. The detected intermediate frequency signals are first down converted to baseband with I/Q separation.
