Abstract: | The multi‐carrier transmission signal in Multi‐Carrier Code Division Multiple Access (MC‐CDMA) has a high peak‐to‐average power ratio (PAPR), which results in nonlinear distortion and deteriorative system performance. An n‐tuple selective mapping method is proposed to reduce the PAPR, in this paper. This method generates 2n sequences of an original data sequence by adding n‐tuple of n PAPR control bits to it followed by an interleaver and error‐control code (ECC) to reduce its PAPR. The convolutional, Golay, and Hamming codes are used as ECCs in the proposed scheme. The proposed method uses different numbers of the n PAPR control bits to accomplish a noteworthy PAPR reduction and also avoids the need for a side‐information transmission. The simulation results authenticate the effectiveness of the proposed method. |
