Abstract
The current literature approaches the subject of communications from the optimum detector point of view, utilizing the principles set forth by Shannon, Davenport, Root, Bode, Peterson, Birdsall, Fox, Weiner, Siebert, Middleton, and many others to carry out detailed analysis of specific detectors, filters, and synchronization processes. This paper approaches communications from a systems point of view, dealing specifically with the family of pseudo-noise systems. The systems discussed are categorized into two groups, the pseudo-noise carrier and the pseudo-noise sub-carrier systems, with emphasis on multiplex techniques. All of the systems discussed are negative dB S/N systems with the exception of a wide-band TV video channel, and a detailed analysis of a representative pseudo-noise sequence of length 15 is given as a background in the auto-correlation functions, power spectral densities, and self-noise spectra which are the characterizing parameters of these waveforms.
