DIGITAL PREDISTORTION DEVICE FOR IMPROVING LINEARITY OF POWER AMPLIFIER

摘要

The present invention relates to a digital predistortion device which includes a data section selection part for an input signal, a section power amplifier modeling constant outputting part corresponding to the selected section, a part to output the input signal delayed by synchronization with the section power amplifier modeling constant, and a digital predistortion processing part. The implementation and performance of the apparatus are improved by applying a digital predistortion algorithm to each data section. The section is flexibly set and the consumption of a hardware resource is reduced by using only one apparatus.;COPYRIGHT KIPO 2014
