Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for a time-domain sequence x(i), an output sequence s(k). The output sequence s(k) is an inverse Fourier transform of a frequency-domain sequence S(j). S(j) is an output of a frequency-domain shaping operation based on a frequency-domain sequence Y(j) and a set of coefficients. Y(j) corresponds to the time-domain sequence x(i) based on a parameter N. The number of non-zero coefficients in the set of coefficients is based on N, and values of the non-zero coefficients correspond to phase values distributed between 0 to π/2 to reduce a peak to average power ratio of the output sequence. The method also includes generating a waveform using the output sequence s(k).
