Being a multicarrier modulation scheme, Orthogonal Frequency Division Multiplexing (OFDM) systems generally produce transmit signals with high Peak to Average Power Ratio or PAPR. Amongst numerous PAPR reduction strategies found in the literature, a relatively new but promising technique is the null and data subcarrier switching method. In this paper, we propose a new approach of null-data subcarrier switching that can achieve acceptable PAPR reduction with significantly less computational… CONTINUE READING
