Communications method and apparatus include encoding information into a high-peakedness designed pulse train, converting the designed pulse train into a low-peakedness signal suitable for modulating a narrowband carrier to generate a physical communication signal with desired spectral and temporal properties, and generating and transmitting the physical communication signal. The communications method and apparatus also include receiving and demodulating the physical communication signal, and further converting the demodulated signal into a high-peakedness received pulse train corresponding to the designed pulse train, so that the encoded information may be extracted from the received pulse train.

A method, computer program, and system for real-time signal analysis providing characterization of temporally-evolving densities and distributions of signal features of arbitrary-type signals in a moving time window by tracking output of order statistic filters (also known as percentile, quantile, or rank-order filters). Given a raw input signal of arbitrary type, origin, or scale, the present invention enables automated quantification and detection of changes in the distribution of any set of quantifiable features of that signal as they occur in time. Furthermore, the present invention's ability to rapidly and accurately detect changes in certain features of an input signal can also enable prediction in cases where the detected changes associated with an increased likelihood of future signal changes.
