Abstract
Future generations of wireless communications are expected to place increasing burdens on the efficiency and linearity of power amplifiers, due to the use of more complex multi-carrier waveforms and OFDM. This has implications for the design of transmitters in portable/mobile devices as well as base stations and access points. This paper will summarize the digital predistortion techniques that can be employed to improve the performance of wireless power amplifiers.
