Dear Mr. Vyas,

Could you give us more insight on your problem by (i.e. showing us a piece of matlab code)? Is it correct that you want to calculate the peak-to-average power ratio (PAPR) for one of the signals that use a MC-CMDA (Multi-Carrier Code Division Multiple Access)?

Kind regards, Christiaan
