摘要
Peak-to-average ratio (PAR) of a signal is an important parameter. It determines the input backoff factor of the amplifier to avoid clipping and spectral regrowth. In this letter, we analyze and compose the PAR of the downlink signal for IS95 and the CDMA2000 single-carrier systems. It is found that PAR of the transmitted signal depends on the walsh code assignment. Furthermore, we found that the PAR of CDMA2000 signal is always lower than the IS95 signal. Finally, PAR control by walsh code selection is proposed.
