SCATTER COMMUNICATION MODELS FOR SPACE VEHICLES,

Abstract

Communication over a multipath link is inherently a more difficult process than single path communication. Multipath communications are characterized by imperfect knowledge of signal waveforms when they arrive at a receiver. Under the assumption that this signal waveform is a sample function of a Gaussian random process, a pulseamplitude-modulation communication system is designed. Optimum receiver data processing and optimum message encoding procedures are derived as a function of the signal and additive noise statistics. When the mean of the pulse signal waveform at the receiver is zero, the optimum code is orthogonal. On the other hand, when the covariance function of the Gaussian signal approaches zero, a regular simplex code provides optimum communications. (Author)
