A Novel Low Complexity and Precise Transceiver IQ skew Calibration Method for Single Carrier Coherent System.
Optical Fiber Communications Conference and Exhibition(2024)
Abstract
We propose a novel precise transceiver IQ skew calibration method utilizing the specially designed training signal for single carrier coherent system. The results show that the estimation error can be within ±0.2ps.
