An algorithm for modeling radio-receiving channels using Volterra func
tional series is proposed. The Volterra series of a channel are define
d in terms of a differential-Taylor spectrum, formed from the coeffici
ents of multidimensional Maclaurin series, obtained for the harmonic c
omponents of the response. An expression is derived for the output sig
nal of a channel with two inputs in the form of a Volterra series.
