Method of allocating carrier frequencies for the simultaneous transmission of several modulated signals, particularly over an optical link

Abstract From the Canadian patent

This process is such that the said carrier frequencies are selected from the form: f = (2p+1)n k where "p" is a whole number representing each carrier frequency "n" is a given frequency band width, and "k" is a given frequency band width possibly nil, less than "n", with, either n is selected large enough in relation to the width of the frequency channels occupied by the said modulated frequencies so that in the case where "k" 0, second order composite beats fall outside the said channels or, if n is large enough in relation to the width of the said channels or the widest among them in case all these channels are not equal in width the transmission system sized so that second order …
