In this paper, the effective use of peak reduction carrier (PRC) for PAPR reduction is evaluated. By taking into account the number of PRCs, its position and PRC-to-Data ratio, the recommendation on how to effectively adopt PRC for PAPR reduction is carried out for OFDM systems with sub-carriers from 64 sub-carriers to 8192 sub-carriers. From our simulations, it has been shown that there are effective positions for PRC allocation as well as a balance needs to be strike for transmission efficiency versus PAPR reduction effectiveness evaluated via the PRC-to-Data ratio.
