Frequency-Domain Digital Predistortion for OFDM

In this letter, a novel frequency-domain (FD) digital predistortion (DPD) solution for orthogonal frequency division multiplexing (OFDM) transmitters (TXs) is proposed. The proposed approach allows to flexibly control the linearization performance, in FD, such that different degrees of linearization can be provided at different parts of the spectrum. Such a feature can be of special interest in th...
