Abstract
The system and method for joint compensation of power amplifier's distortion provides a linearization scheme for transmitter power amplifiers driven by orthogonal frequency division multiplexing signals. A pre-compensated over-driven amplifier is employed at the transmitter. The over-driven amplifier's distortions are considered as a sparse phenomenon and compressive sensing (CS) algorithms are employed at the receiver to estimate and compensate for these distortions. A bandwidth efficient data aided scheme which does not require reserving subcarriers specifically for CS measurements is utilized.
