US 11,050,591 B2 · Method and apparatus for nonlinear filtering and for secure communications

Abstract

Method and apparatus for nonlinear signal processing include mitigation of outlier noise in the process of analog-to-digital conversion and adaptive real-time signal conditioning, processing, analysis, quantification, comparison, and control. Methods, processes and apparatus for real-time measuring and analysis of variables include statistical analysis and generic measurement systems and processes which are not specially adapted for any specific variables, or to one particular environment. Methods and corresponding apparatus for mitigation of electromagnetic interference, for improving properties of electronic devices, and for improving and/or enabling coexistence of a plurality of electronic devices include post-processing analysis of measured variables and post-processing statistical analysis. Methods, processes and apparatus for secure communications include low-power communications and physical-layer steganography.

Dependent claims

A communication apparatus capable of conveying information from a transmitter to a receiver,

wherein said transmitter comprises:
a) a means for encoding said information into a transmitter pulse train, wherein said transmitter pulse train is characterized by limited bandwidth and by high peakedness;
b) a means for converting said transmitter pulse train into a modulating component, wherein said modulating component is characterized by said limited bandwidth and by low peakedness;
c) a means for utilizing said modulating component for generation of a physical communication signal, and
d) a means for transmitting said physical communication signal;
wherein said receiver comprises:
e) a means for receiving said physical communication signal;
f) a means for converting said physical communication signal into a demodulated signal comprising said modulating component;
g) a means for converting said modulating component into a receiver pulse train characterized by said limited bandwidth and by high peakedness, and
h) a means for extracting said information from said receiver pulse train.
