MULTI-DIMENSIONAL VOLTERRA SERIES TRANSMITTER LINEARIZATION DEVICE, PARTICULARLY FOR IMPROVING THE PERFORMANCE OF THE WHOLE SYSTEM

摘要

PURPOSE: A multi-dimensional volterra series transmitter linearization device is provided to improve the amplified signal linearization.;CONSTITUTION: A PA(Power Amplifier)(250) is coupled to plural VE(Volterra Engine) linealizers, and a feedback circuit(260) is coupled to the VE linealizers and the PAs. At least one adaptive controller(270) is coupled to the feedback circuit, and each VE linealizer is connected to the VE linearlization through serial or parallel connection or both serial and parallel connections. The VE linearlizer compensates a distortion aspect for the output signal from the PA.;COPYRIGHT KIPO 2010
