Method and system for pre-compensating non-linear distortion in data samples

A method for pre-compensating non-linear distortion in data samples, the method comprising:

• generating a first set of data symbols to be transmitted;
• converting the first set of data symbols into a first set of frequency-domain samples;
• pre-processing the first set of frequency-domain samples;
• providing linear distortion compensation, prior to compensating for non-linear distortions, to the pre-processed first set of frequency-domain samples;
• converting the linear distortion compensated first set of frequency-domain samples into linear distortion compensated first set of time domain samples;
• and
• providing non-linear distortion compensation to the linear distortion compensated first set of time domain samples.

A system for generating a Pattern Dependent Lookup Table (PDLUT), the system comprising:

• a non-transitory memory element having instructions thereon;
• at least one processor coupled to the non-transitory memory element and which execute the instructions to cause the at least one processor to:
• receive consecutive sequences of samples included in a first set of time domain samples;
• quantize the consecutive sequences of samples into integer-valued consecutive sequences of samples;
• compute error correction values corresponding to the integer-valued consecutive sequences of samples;
• and
• store the integer-valued consecutive sequences of samples and the corresponding error correction values in the PDLUT.
