Abstract :
The authors provide a characterization of a space-time channel for a turbulent or material media such that the physics of the media can be incorporated. The characterization is made by introducing the notion of a space-time channel transmittance function. The space-time input-output response of the channel is characterized in terms of a set of space-time superposition integrals. Using the concepts of correlation time, distance, and a space-time sampling theorem, a four-dimensional space-time channel model is presented in the form of a space-time tap-delay model. This model is reduced to a two-dimensional model and the similarities and differences to earlier work of T. Kailath (1959) and P.A. Bello (1963) are discussed.<>
