摘要：
A selective scrambling technique is proposed for reducing the peak to average power ratio (PAPR) in QPSK-OFDM systems, while incurring negligible redundancy. Formulation of an appropriate function for selecting between scrambled sequences is discussed, and simulation shows that scrambling reduces the PAPR of the OFDM signal to typically 2% of the maximum possible value.
