A Modified Adaptive Pre-distorter for Power Amplifier in OFDM Systems
This paper focus on the LUT based digital pre-distortion techniques for non-linear power amplifier in OFDM systems. Compared with the conventional adaptive pre-distortion method, a modified method is proposed, which utilizes interpolation algorithm, with a consideration of the amplitude distribution characteristic of OFDM symbols. The performances of the conventional and modified algorithms are compared in terms of the simulation results and analysis, which demonstrates the performance of the modified method is more outstanding.
