A single-carrier signal is generated from a number, N, of symbols in a way that results in a low PAPR. This includes generating an initial set of N complex frequency components from the N symbols. N<SUB>s </SUB>different sets of N complex frequency components are generated by, for each of N<SUB>s </SUB>times, permuting the initial set of N complex frequency components by one of N<SUB>s </SUB>possible permutations. N<SUB>s </SUB>different sets of M complex frequency components are generated by mapping each of the N<SUB>s </SUB>different sets of N complex frequency components onto a set of M carrier frequencies. After shaping, an IDFT generates a candidate set of N time-domain symbols from each of the N<SUB>s </SUB>different sets of M complex frequency components. That one of the N<SUB>s </SUB>different candidate sets of N time-domain symbols that is associated with the smallest PAPR is selected for further processing.
