Abstract

Radio spectra in space are close-packed more and more, so its impact of frequency as a valuable resource is increasingly prominent. Based on reviews of those classical methods a communication engineer accustomed to, this paper will interpret the theoretic foundation and key technology of the Ultra Narrow Band (UNB) modulation and demodulation, and gives a system scheme for UNB transmissions. This UNB scheme includes a unitive expression for extending of binary phase modulations, a realization of its modulator and demodulator (MODEM), and especially an important UNB filter. Applications to space communication of the proposed high data rate UNB MODEM are discussed.
