摘要 用高功率放大器放大线性调制信号 (包络波动变化 ) ,必然会产生失真和互调成分。而基于扩频技术的第三代无线通信系统中的功率放大器必须要有很好的线性性能。本文提出一种线性化射频多载波高功率放大器的自适应射频预失真器。 Amplification of linear modulation schemes, (which exhibit fluctuating envelopes), by high power amplifiers invariably leads to the generation of distortion and intermodulation products. Power amplifiers (PA) used in 3G wireless communication systems based on spread spectrum techniques must exhibit exceptional linearity. This paper presents an adaptive RF predistorter to linearize multi-carriers power amplifiers.
