Abstract :
This paper presents an iterative random interleaver design (IRID) scheme for reducing the high peak-to-average power ratio (PAPR) of orthogonal frequency-division multiplexing (OFDM) systems. The main idea is based on utilizing a processing of iteratively interleaving with only one fixed pattern for saving the memory size of conventional transmitter and receiver. Numerical simulation results show that the proposed IRID scheme is with identical PAPR reduction performance with the conventional scheme by introducing only one fixed interleaving pattern.
