ABSTRACT:
A method and system are provided to compensate for the nonlinearity of a wireless transmitter. The method includes sending a predetermined input bit stream to the power amplifier, calculating the coefficients of the polynomial representing the response curve of the power amplifier and generating the predistortion coefficients of the polynomial representing the response curve of the predistortor. The method linearizes the response curve of the transmitter chain in a communication device.
