Explicit solution for DFE optimization with constraints
19 Sep 23
A method of equalizing a communication link includes setting a number of coefficients to a required number, determining a number of pulse responses for a waveform, setting all values in a set of values to zero, repeating, until all values have been assigned, determining a current lowest parameter, using a position of the current lowest parameter as an index, determining a minimum value between a first term multiplied by a main pulse response minus a summation of each parameter multiplied by each value, divided by the current lowest parameter, and a corresponding pulse response, and assigning the minimum value to the value having a position equal to the position of the current lowest parameter, and determining a value of each coefficient in a set of coefficients by multiplying each value with the sign of a corresponding pulse response; defining an equalizer having a number of taps having a value based on the corresponding coefficient; and applying the equalizer to a waveform.
