  • Publication number: 20230291615
    Abstract: 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.

  • Patent number: 11050591
    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.
