Transmitter IQ Skew Estimation for Alamouti Coding-Based Simplified Coherent Systems

IEEE Photonics Journal
The simplified coherent system combining Alamouti coding and single balanced photodetector reception has emerged as a promising solution for short reach scenarios. However, Alamouti coding is one kind of space-time coding that has a higher requirement on

Time varying ISI model for nonlinear interference noise

, 2013
We show that the effect of nonlinear interference in WDM systems is equivalent to slowly varying inter-symbol-interference (ISI), and hence its cancellation can be carried out by means of adaptive linear filtering.
