Abstract
Embodiments include a system for performing electronic dispersion compensation on an information-bearing signal transmitted over a communication channel. The system may include a channel identification module configured to receive a first digitized version of the information bearing signal and an equalized version of the information-bearing signal, and may be configured to determine an impulse response of the communication channel based thereon. The system may include a time varying phase detector configured to receive the equalized version of the information bearing signal, a second digitized version of the information-bearing signal, and the impulse response, and may be further configured to generate a reference wave based on the impulse response and the equalized version of the information-bearing signal. The time varying phase detector may be configured to generate a phase signal based on the reference wave and on an error signal determined from the reference wave and the second digitized version of the information-bearing signal.
