Electronic dispersion compensation utilizing interleaved architecture and channel identification for assisting timing recovery

A method for performing channel identification for a communication channel comprising:

• computing a plurality of impulse response signals for the communication channel, wherein each of the plurality of impulse response signals is associated with a distinct phase;
• determining an optimal impulse response signal of the plurality of impulse response signals for the communication channel;
• determining a reference wave, based on the optimal impulse response signal;
• determining an error signal between the reference wave and a corresponding portion of an information-bearing signal transmitted over the communication channel;
• and
• determining a phase signal for controlling a timing recovery circuit based upon the reference wave and the error signal.

A system for performing electronic dispersion compensation on an information-bearing signal transmitted over a communication channel, the system comprising:

• 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 configured to determine an impulse response of the communication channel based thereon;
• and
• 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 further configured to generate a reference wave based on the impulse response and the equalized version of the information-bearing signal,
• wherein the time varying phase detector is 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.
