In this paper, the problem of reducing the peak-to-average power ratio (PAPR) of a discrete Fourier transform-spread orthogonal frequency-division multiplexing signal is considered for the transmission of constellation-rotated QPSK symbols. In particular, a joint optimization of the constellation-ro...
