摘要 正交频分复用-连续相位调制(OFDM-CPM)系统通过CPM相关相位状态引入记忆,从而获得比传统调制方式更好的误码性能。降低OFDM-CPM系统中的峰值平均功率比(PAPR)是关键技术之一。利用恒包络的概念提出一种新的CE-OFDM-CPM调制方案,可以把OFDM-CPM系统的PAPR降至零分贝。 Orthogonal frequency division multiplexing-continuous phase modulation (OFDM-CPM) system introduces memories using the concept of correlated phase state. Thus its BER performance is better than the conventional OFDM system. One of the key techniques is to reduce the peak-to-average power ratio (PAPR) of the OFDM-CPM system. Using the concept of constant envelope (CE), a novel modulation scheme CE-OFDM-CPM is proposed in this paper. The PAPR of OFDM-CPM can be reduced to 0 dB.
