Research And Realization On RF Signal PAPR Reduction In CDMA2000 BTS System

HighPeak-to-AverageRatiohasbadinfectiontotheapplicationinCDMABTS.Firstly, the conception of Peak-to-Average Ratio was illustrated, and the reason ofhigh peak-to-average ratio of RF signal in CDMAmobile system was analyzed. Then,several schemes of PAPR reduction which adapt to RF subsystem in CDMA2000 BTSwere studied. Furthermore, two realization schemes of PAPR reduction by using pulsecompensationwerediscussedindetail.Accordingtothecomparisonofthetwoschemes,an improved realization scheme of PAPR reduction by using pulse compensation waselicited. The scheme of PAPR reduction by using pulse compensation and the improvedscheme of PAPR reduction by using pulse compensation were realized and simulated.The data of simulation proved that the improved scheme of PAPR reduction by usingpulsecompensationwasmoreeffective.
