Abstract: An example apparatus includes: programmable circuitry to receive an input signal, a digital pre-distorter (DPD) output signal, and a power amplifier (PA) feedback signal; populate a partial matrix with a threshold number of rows of equation terms; compute a respective observation terms for each row in the threshold number of rows; reduce the partial matrix into a Hermitian matrix and reduce the observation terms into a vector; accumulate the Hermitian matrix and the vector onto the memory; regularize, after a determination that a threshold number of Hermitian matrices have been accumulated, the memory to form an output matrix; and pre-distort the input signal using the output matrix.
