A novel peak-to-average power ratio (PAPR) reduction scheme designed as extended selected mapping (eSLM) for space-frequency block coding (SFBC) multi-input multi-output orthogonal frequency division multiplexing systems. In the eSLM method, it creates extension matrices comprising amplitude extensions and phase rotations to get the selected signal index with no side information and to reduce the PAPR, respectively. To minimize the computational complexity obtained by the IDFT operation in generating the candidate signals, a low-complexity eSLM scheme (LC-eSLM) is generated by establishing equivalent candidate signals in the time domain. Particularly, the extension matrices in both designs preserve the orthogonality of the SFBC code, promoting low-complexity decoding. The simulation results illustrate that the proposed eSLM scheme not only out performs existing blind SLM-based schemes. Compared with the valuable ordinary SLM scheme, the eSLM scheme involves a lowePr computational complexity with a work loss of less than 0.3 dB and causes no side information. The computational complexity of the LC-eSLM scheme is around 40%–50% lower than that of the eSLM scheme with only a minimal degradation in the PAPR reduction performance
