Abstract
The thermodynamics-based signal receiver transforms contiguous segments of a received signal into thermodynamics-related quantities using an analog of a statistical-mechanics-related quantities using an analog of a statistical-mechanics expression for a thermodynamic variable and uses these thermodynamics-related quantities as the means to measure changes in the signal as a function of time or origin. The changes that are of interest are those associated with either signal level or signal structure. Signal-processing analogs of statistical mechanics expressions for thermodynamic variables are measures that respond in some fashion to either type of change. By comparing thermodynamics-related transformations of received signals, one can obtain information about the emitters of the received signals and the nature of the medium through which the signals were propagated. The sensitivity of the thermodynamics-based receiver is significantly better than the more conventional signal energy-based receiver in detecting the changes in a signal that result from reflection or scattering by inhomogeneities in a wave-propagating medium.
