A Modified Band-Limited Digital Predistortion Technique for Broadband Power Amplifiers

In this letter, a modified band-limited digital predistortion (DPD) technique is proposed to improve the performance of the conventional band-limited DPD method in wideband systems. The power amplifier's (PA's) spectral regrowth outside the passband of bandpass filter is unable to be compe...
