We propose a blind transmitter (Tx) and receiver (Rx) in-phase/quadrature (IQ) amplitude
and phase imbalances estimation scheme based on a combination of analytical modeling …

A self-calibration procedure for an optical transmitter is provided. During the self-calibration
procedure, a phase bias of an optical modulator of the optical transmitter is set so that an in …

A bio-inspired detector based on the artificial neural network (ANN) and genetic algorithm is
proposed in the context of a coherent optical transmission system. The ANN is designed to …

We investigate transmitter IQ imbalance compensation based on the blind adaptive source
separation (BASS) method in a dual-polarization M-QAM optical coherent system. The …

High precise IQ skewcalibration of the coherent optical transceiver is crucial for high baud
rate and high-order modulation formats optical transmission system. In this paper, a novel …

The self-homodyne coherent detection (SHCD) system is becoming more popular in intra-
data center applications nowadays. However, for a high-speed SHCD system, the device …

One of the major impediments in the design and operation of a full-duplex radio transceiver
is the presence of self-interference (SI), that is, the transceiver's transmitted signal, 60–100 …

One or more operational parameters associated with pluggable optical transceivers are
estimated to mitigate impairments to an optical signal caused by imperfections in the optical …

A novel joint polarization demultiplexing and IQ imbalance compensation scheme for
coherent optical communications that uses global update is proposed and analyzed through …
