Abstract

Recently, a hybrid single carrier(SC) and multi-carrier (MC) system based on the 4-weighted fractional Fourier transform (4-WFRFT) was proposed. As this hybrid carrier (HC) system contains MC component, it inherits the problem of high peak to average power ratio (PAPR). In this paper, we investigate the clipping technique for PAPR reduction in HC system. By analysis and simulation, we show that clipping technique is a simple and efficient way to overcome the large PAPR in HC system at the price of increased bit error ratio (BER). Furthermore, a higher MC proportion in HC leads to a worse BER performance.
