Fig. 6From: Low-complexity selective mapping technique for PAPR reduction in downlink power domain OFDM-NOMASum rate capacity of DL OFDM-NOMA in the presence of nonlinear distortion before and after using conventional and proposed SLM techniques, with different numbers of alternatives \(I=64\) and \(I=256\), compared with the sum rate capacity of DL OFDM-NOMA and DL OFDM-OMA in ideal caseBack to article page
