Abstract :
Repeated clipping and filtering is an effective peak reduction method to achieve a desired peak-to-average power ratio for OFDM. An efficient implementation of the repeated process in which no IFFT and FFT are required is presented. The complexity of the new implementation is much less than that of the original method.
