AGP–NCS Scheme for PAPR Reduction

In this paper, a combinational method is proposed for peak-to-average power ratio reduction in orthogonal frequency division multiplexing systems using approximate gradient-project with null-subcarriers switching (AGP–NCS) scheme. The key idea of the proposed method is to generate a dynamically extended outer constellation points using AGP method with exploiting the concept of NCS process. The proposed method substantially reduces peak-to-average power without sacrificing the bit error rate. Moreover, proposed scheme requires no channel side information during transmission, therefore shows no reduction in data rate. The simulation results of proposed method show a better performance when compared with other methods.
