Electronic Predistortion for Compensation of Fiber Transmission Impairments - Theory and Complexity Considerations

Over the last few years, electronic signal processing methods for the mitigation of transmission impairments in fiber-optic communication systems have attracted a lot of attention. Some particular advantages compared to optical compensation techniques are an increased flexibility and possible adaptation to changing link conditions as well as ease of integration. In addition to that, these techniques are now becoming feasible in practice due to recent advances in highspeed electronics. Different studies have targeted the compensation of Chromatic Dispersion (CD) after direct-detection. Some of the proposed techniques are based on digital filtering using FEedForward- (FFE) and Decision-FEedback (DFE) equalizers.
