A technique for reducing peak-to-average power ratio (PAPR) in digital signal communications is disclosed. In one particular exemplary embodiment, the technique may be realized by a method comprising the steps of modulating a frequency-domain input vector comprising a plurality of path vectors by applying a Gray code sequence of combinations of binary phase rotations to the plurality of path vectors, where, in each combination, the binary phase rotation of only one of the plurality of path vectors is changed from a previous combination in the Gray code sequence; and determining an optimal time-domain peak value based on the modulated frequency-domain input vector.
