Abstract
Peak-to-average ratio (PAR) of a signal is an important parameter for a linear amplifier because it determines the backoff factor needed to be applied to the amplifier in order to avoid clipping and hence spectral regrowth. The author analyses and compares the PAR of the downlink signal for the IS-95 and the CDMA2000 single carrier systems. It is found that PAR of the signal depends on the Walsh code assignment. PAR control by Walsh code selection is proposed and its effectiveness is discussed.
