Low Computation Complexity Two-Stage Feedforward Carrier Recovery Algorithm for M-QAM
Low Computation Complexity Two-Stage FeedforwardCarrier Recovery Algorithm M-QAM
2015/5/20
We propose a modified two-stage feedforward carrier recovery algorithm for M-QAM formats that achieves a 3x reduction in computation complexity compared to a single-stage algorithm. When combining wit...
Pseudo-Newton based Equalization Algorithms for QAM Coherent Optical Systems
Coherent communications Optical communications
2015/6/8
In 112Gbit/s optical coherent transmission context, we propose decision-directed and blind adaptive equalizers using variable step size suitable for 16-QAM. The considered algorithms offer better stea...
Performance of Modified Decision-Directed Polarization Control/Demultiplex Algorithm in Coherent QAM Receiver
Coherent communications Optical communications
2015/6/4
A modified decision-directed polarization control and demultiplex algorithm for coherent receivers is evaluated for QAM schemes up to order 256, and compared against the constant-modulus algorithm ada...
QAM Adaptation of Constant-Modulus Algorithm and Differential Phase Compensation for Polarization Demultiplex in Coherent Receiver
QAM Adaptation Constant-Modulus Algorithm Differential Phase Compensation Polarization Demultiplex Coherent Receiver
2015/7/16
The constant modulus algorithm is adapted for QAM signals and complemented with a differential phase compensation. This triples polarization control speed and doubles laser linewidth tolerance.
