Concentration of Binary FM Spectra
The spectrum of a digital FM signal can be considered as an indicator of the resistance of the signal to distortions caused by band-limitation. The study in this paper is oriented toward the design of a signaling pulses that will achieve a concentrated about the carrier frequency FM signal spectrum. Convenient spectrum expressions and general guarantees of optimality are found for FSK signals.
