Abstract
We study the joint effects of transmitter in-phase/quadrature-phase (IQ) mismatch, channel distortion, and laser phase noise in a coherent optical orthogonal frequency-division-multiplexed system. We propose a decision-aided joint compensation scheme, which separates the transmitter IQ mismatch as well as channel distortion and phase noise compensation into two consecutive steps. Simulation results show this novel technique to be effective in mitigating the three effects simultaneously.
