Abstract :
In this paper, we propose a simple peak-to-average power ratio (PAPR) reduction algorithm for code-division multiple access (CDMA) systems. The described algorithm is based on predistorting a set of symbols using an appropriate metric and does not need sending any side information to the receiver. Using binary phase-shift keying (BPSK) modulation, we show that performance of this algorithm approaches that of the optimum PAPR reduction procedure while avoiding its excessive complexity
