In particular embodiments, a method includes receiving as an input signal a phase-distorted signal or a transmitted-data signal, the phase-distorted signal having been distorted from a phase-equalized signal by transmission across a communication channel, the transmitted-data signal comprising transmitted data; generating a non-derivative version of the input signal by applying a delay operator in a continuous-time domain to the input signal; generating a derivative version of the input signal by applying a derivative operator in a continuous-time domain to the input signal; generating a first product signal by multiplying the non-derivative version of the input signal by a first coefficient, the first coefficient being a positive number; generating a second product signal by multiplying the derivative version of the input signal by a second coefficient, the second coefficient being a negative number; and generating an output signal by summing the first and second product signals.
