Originální abstrakt
Present wideband and spectrally-efficient communication systems require linear transmitters. As power amplifiers are naturally nonlinear, the linear transmitter is often achieved by application of a digital predistorter (DPD). DPDs require system bandwidth to be higher than communication bandwidth. We provide an evaluation of influence of the reconstruction and anti-aliasing filter on quality of predistortion process. Our results show that the generally accepted rule is too demanding and the actual required filters bandwidth is lower. This has direct impact on required sampling rates of system converters.
