Abstract
This letter presents a computationally efficient scheme to mitigate the effect of phase noise, including intercarrier interference, in coherent optical orthogonal frequency-division-multiplexing systems. Utilizing the fact that phase noise in the time domain can be modeled as a circular convolution with a finite impulse response filter in the frequency domain, and its matched filter is the optimal solution to cancel the phase noise, semiblind adaptive channel equalization algorithms are applied to directly remove the effect of phase noise without the estimation process. Simulation results demonstrate substantial improvement in phase noise suppression using the proposed algorithm.
