Abstract

A method for geometric harmonic signal modulation consisting of harmonics equidistant from each other by frequency for coding each symbol of the transferred data comprises using the a random or pseudorandom set of differences of initial pairs of nearest harmonic pairs. Said difference sets of the initial phases are selected in such a way that the peak factor of an added signal is minimised.
