Abstract
An optical communication system with nonlinear equalization capability for equalizing distortions of a data communication channel, which comprises a processor for periodically gathering a predetermined number of consecutive data segments from an input data stream to a group and adding a known pilot sequence to the group, thereby forming a data frame; an optical transmitter at the input of the channel, for transmitting the data frames to a receiver, over the channel; a receiver at the output of the channel, for detecting the transmitted frames, the receiver including a demodulator. The demodulator is adapted to recover the pilot sequence of each frame; compare each recovered pilot sequence which its corresponding original transmitted pilot sequence; extract the current Channel State Information indicative of changes in the channel distortion, using the comparison results; use changes in the Channel State Information for updating the coefficients of the estimator and of the equalizer, every time a frame is received; and equalize the channel estimator and of said equalizer, every time a frame is received; and equalize the channel using the equalizer coefficients, and based on the current Channel State Information.
