Abstract

This paper analyzes the crash factor (CF) for multicarrier code division multiple access (MC-CDMA) communication system. The CF (or peak to average power ratio - PAPR) is critical in multicarrier orthogonal systems (based on orthogonal frequency division multiplex - OFDM). The amplitude statistics for system are computed and gamma distribution is considered for amplitude distribution modeling. The distribution parameters are estimated for different scenarios (different number of users in system). The usability for PAPR reduction is discussed.
