从两个方面对OFDM系统中峰值功率的降低和处理方法进行了综述。一类是从OFDM信号着手,包括编码技术、相位旋转方法、剪截法或者限幅法;另一类方法是对高频功率放大器的实现方面着手,主要是放大器预失真方法。
The reduction and processing of peak power in OFDM system are reviewed from two aspects. One is to start from the OFDM signal, including encoding technology, phase rotation method, clipping method or clipping method; the other method is to achieve the high-frequency power amplifier, mainly amplifier pre-distortion method.
