A Characterization of the Multipath in the HDTV Channel

Abstract: The Institute for Telecommunication Sciences (ITS) has recently completed a program to measure the impulse responses of channels that would probably be used in over-the-air HDTV. To help in the analysis of these measurements, we have developed a simple statistical model which needs only two parameters together with a rough idea of the "archetypal" surroundings of the receiver. The two parameters --- the "strength" and the "spread" of the "multipath tail" --- then serve as a description of our data and we may tabulate the results versus changes in known system parameters. We may also propose the model as a fairly realistic simulation of "normally observed" multipath.
