Comparative Analysis of Direct and Coherent Detection Methods for Digital Information Optical Signals. Part 2. Coherent Detection
Abstract
In the second part of the article, an analysis is made of the coherent reception of optical digital signals with different modulation formats: amplitude modulation, phase modulation, and quadrature-amplitude modulation. Signal-to-noise ratios and limiting detection capabilities for binary modulation formats are determined. The schemes of heterodyne and homodyne optical receivers are analyzed.
