OFDM技术使得频率选择性信道中能够进行高速数据传输,在无线通信应用中有很好的发展前景,但PAPR(峰值对平均功率比,简称峰均比)较大是其主要缺陷之一。将目前已提出的众多解决方法作了分类比较并着重描述了常用的算法。
OFDM technology makes high-speed data transmission possible in frequency-selective channels and has good prospects in wireless communication applications. However, PAPR (peak to average power ratio) is one of the major drawbacks. A number of solutions that have been proposed so far have been classified and compared, highlighting commonly used algorithms.
