Abstract
In particular embodiments, a method includes generating by a data detector a recovered data signal from a phase-equalized signal based on the transmitted data in the phase-equalized signal; comparing by a phase-distortion detector the phase-equalized signal and the recovered data signal with each other; based on the comparison, determining by the phase-distortion detector a phase-distortion level; generating by the phase-distortion detector a phase-distortion-level signal based on the phase-distortion level; generating by an integrator a phase-equalize-level signal based on the phase-distortion-level signal; and adjusting by a phase equalizer a transmitted-data signal based on the phase-equalize-level signal, the adjustment of the transmitted-data signal providing the phase-equalized signal or a phase pre-distorted signal configured to be distorted into the phase-equalized signal by transmission across a communication channel, the transmitted-data signal comprising the transmitted data.
