| Abstract: | This paper describes the definition and characteristic of the peak-to-average power ratio(PAPR),then gives the reason the multi-carrier wideband CDMA will reduce the PAPR.An improved clipping algorithm is adopted,and feasibility of this algorithm is validated by simulation.The experimental analysis shows that the algorithm has low complexity implement and has relatively good performance in PAPR reduce. |
