ENTROPY BASED SIGNAL TRANSMISSION, RECEPTION AND SIGNAL ANALYSIS METHOD AND APPARATUS

摘要

An entropy based signal transmission (50), reception (58) and analysis method and apparatus in which the entropy of time dependent signals is determined by utilizing a selected Green's function relationship. Information with respect to a medium with which the signals have interacted is derived by comparison of the entropies of the signals. In a preferred embodiment, the density distribution functions of selected digitized time segments (58, 62) of the signals to be analyzed (68) are determined by using the selected Green's function relationship and the entropies of the signals are then determined from the density distribution functions and compared with each other (70) to derive the desired information.
