Real-time IQ Imbalance Compensation for Coherent Optical OFDM Transmission
Fiber optics links and subsystems Coherent communications
2015/5/25
A FPGA-based receiver side (Rx) IQ imbalance compensation scheme for 10.7-Gb/s 16-QAM CO-OFDM transmission is demonstrated in real time. The compensation scheme performs better with the increase of OS...
A Novel Optical Direct-Detection I/Q Up-Conversion with I/Q Imbalance Compensation via Gram-Schmidt Orthogonalization Procedure
Novel Optical I/Q Imbalance Compensation Gram-Schmidt Orthogonalization Procedure
2015/7/20
We proposed RF detect-detection vector signal generation using optical I/Q up-conversion. The Gram–Schmidt orthogonalization procedure is employed to compensate I/Q imbalance. After transmission over ...
