Abstract:

This paper focus on the research of LUT based digital pre-distortion techniques in OFDM systems. The defects of the conventional LUT based pre-distortion techniques are pointed out with the improved method proposed. The performance of the algorithms are compared and analyzed in terms of BER, PSD and the convergence speed. Simulation results and analysis demonstrate the better performance of the proposed method.
