文摘

Two iterative Decision-Directed PAPR reduction methods for optical OFDM are proposed. The proposed methods are applicable to both DCO-OFDM and ACO-OFDM. High PAPR is counteracted by using simple and efficient method of clipping. The proposed methods are less complex as compared to other PAPR reduction methods.
