This report discusses the development and engineering of a suitable quadrupolar probe for simultaneous and noninvasive surveys of electrical resistivity and dielectric permittivity. The quadrupolar pr...
Optical Performance Monitoring of Data Degradation by Evaluating the Deformation of an Asynchronously Generated I/Q Data Constellation
Optical Performance Monitoring Degradation Asynchronously Generated I/Q Data Constellation
2009/7/17
We present a technique of using asynchronously generated constellation pattern to simultaneously monitor CD and first order PMD in DQPSK systems. By characterizing deformations in the patterns, the am...
