Abstract

The input average power and peak power for different numbers of multiple channels are estimated for power amplifiers operated in CDMA-based PCS down-link transmitters. Multiple QPSK spread spectrum signals have been simulated, using SPW software (signal processing worksystem). The simulation results for N⩽64 are given. The obtained dynamic range requirements are useful for linear power amplifiers designed for CDMA-PCS application
