Abstract
There is provided compensation for non-linear effects caused by a radio frequency power amplifier. An input sequence is acquired. A pre-distortion parameter is determined based on the input sequence. The pre-distortion parameter is based on a block matrix pseudo-inverse of a regression matrix comprising permutations of the input sequence. The regression matrix is decomposed into at least two block matrices based on at least one physical property of the radio frequency power amplifier.
