A system and method for achieving crest factor (CF) reduction for multi-carrier modulation in a wireless communication network (100), such as an ad-hoc peer-to-peer multi-hopping mobile wireless communication network (100). The system and method use the properties of the Inverse Fourier Transform (IFT) for achieving crest-factor reduction. Specifically, the system and method map original signal input frequencies to a new set of frequencies by mapping every input frequency to some other input frequency, and then using the IFT to create multiple versions of the transmitted signal and then computing the transform with the lowest CF and selecting that signal for transmission.
