The paper presents an efficient digital adaptive method compensating for nonlinear distortions caused by a high-power amplifier (HPA) in orthogonal frequency division multiplexing(OFDM) system.
本文提出了一种用于正交频分复用（OFDM）系统中由大功率放大器引起的非线性失真的有效的数字自适应补偿方法。
The OFDM system has a major disadvantage that high peak to average power ratio (PAPR) can cause nonlinear distortion in the high power amplifier (HPA).
OFDM系统的一个主要缺陷就是峰平比过高引起的高功率放大器(HPA)的非线性失真。
But the OFDM signal has a large PAPR, which results in the significant nonlinear distortion when it passes through a HPA (high power amplifier), thereby the performances of the system descend.
但是OFDM信号有高的峰值平均功率比，当它通过高功率放大器时会导致非线性失真，从而使得系统的性能下降。
