  • Joint optimization of FIR filters in a non-linear compensator
    Patent number: 11329633
    Abstract: A mechanism is included for jointly determining filter coefficients for Finite Impulse Response (FIR) filters in a Linear, Memory-less Non-linear (LNL), Linear compensator. Calibration signals are applied to a signal converter input in a test and measurement system. Non-linear signal components are determined in signal output from the signal converter. Non-linear filter components are determined at the LNL compensator based on the calibration signals. The non-linear signal components are then compared to the non-linear filter components. The comparison is then resolved to determine filter coefficients for first stage Finite Impulse Response (FIR) filters and second stage FIR filters in the LNL.
