摘要:

针对宽带卫星通信系统中高功率放大器的记忆非线性失真问题，对不同补偿技术进行了综述，重点研究了预失真的学习结构、数据预失真、信号预失真、时频域预失真和自适应均衡等补偿技术并对它们进行了相应的优缺点比较，最后提出了宽带卫星功放实际应用环境下的4种补偿方案，为我国宽带卫星功放失真补偿研究提供理论参考。

Abstract:

As the high power amplifiers(HPA) suffer from memory nonlinear distort ion in wideband satellite communication system, which downgrades its performance drastically, different nonlinear distortion compensation techniques are reviewe d in this paper. Predistortion learning architecture, data predistortion, si gnal predistortion, time and frequency domain predistortion and adaptive equ alization are focused, at the same time, advantages & disadvantages and applicat ions of these techniques are compared and analyzed. Finally, four compensation s chemes in practical applications of wideband satellite amplifiers are proposed to provide a theoretical reference for China′s highspeed satellite amplifier distortion compensation research.

Key words: wideband satellite communication power amplifier nonlinear distortion digital pre distortion compensation scheme
