Abstract:
A reduced cost method for the measurement and correction of residual nonlinearities in a digitally predistorted transmitter is disclosed. Systems employing predistorters and power amplifiers are calibrated by processing actual input and output signals during the normal operation of the systems. The systems correct memoryless nonlinearities as well as both memoryless and memory based nonlinearities.
