摘要 本文针对无线OFDM系统中功放非线性的影响,提出了基于基带预失真技术的解决方案。通过计算机仿真考查其对不同功放特性的自适应有效性,结果表明该基带预失真技术对OFDM系统的功放非线性恶化改善明显。 This article deals with the base-band predistortion to compensate for the nonlinear effect of the RF high-power amplifier in wireless OFDM system. Through computer simulation, the adaptive performance of the predistorter proposed for OFDM system is ana- lyzed with different power amplifier models. Simulation results show the efficient performance of proposed scheme to compensate for the nonlinear distortion of the power amplifier.
