Abstract :
The effect of Walsh code assignment and data correlation on the peak-to-average power-ratio (PAPR) of a downlink CDMA signal is investigated. A PAPR-reduction algorithm is proposed using data reversal and channel hopping. Simulations show that improved PAPR reduction and bit-error rate performance can be achieved by the proposed algorithm.
