Abstract

In mobile communications, power efficiency is an important factor in the design of the handset. HPSK modulation is used to transmit multiple channels in the reverse link of cdma2000. In this paper, we propose an improved scheme that includes zero phase transition and zero crossing reduction can reduce the peak-to-average power ratio (PAR) of the HPSK signals. The improved scheme is analysed. The scheme can reduce the PAR obviously. The zero crossing rate reduction can reduce the out-of-band power effectively. The simulation results are given and prove the validity of the schemes.
