It is well known that the high peak-to-average power ratio (PAPR) and large spectrum sidelobe power are two main drawbacks at the transmitter in noncontiguous orthogonal frequency-division multiplexing (NC-OFDM)-based cognitive radio (CR) systems. In this paper, we propose a novel signal cancellation (SC) method for joint PAPR reduction and sidelobe suppression in NC-OFDM-based CR systems. The key idea of the proposed method is to dynamically extend part of the constellation points on the… CONTINUE READING
