  • Windowing methods and systems for use in time-frequency analysis
    Patent number: 10455426
    Abstract: The present embodiments include methods of time-frequency analyzing signals. Some embodiments provide methods of processing signals comprising: adaptively partitioning at least a portion of a signal in a time domain into a plurality of segments of the signal; and transforming each of the segments of the signal producing respective expansions in a frequency domain and obtaining respective samples of the windows of signal in the frequency domain.
    Type: Grant
    Filed: September 23, 2016
    Date of Patent: October 22, 2019
    Assignee: AMERICAN UNIVERSITY

  • Windowing methods and systems for use in time-frequency analysis
    Patent number: 9454511
    Abstract: The present embodiments include methods of time-frequency analyzing signals. Some embodiments provide methods of processing signals comprising: receiving a communication signal; adaptively partitioning the signal in a time domain into a plurality of windows of the signal; transforming each of the windows of the signal producing respective expansions in a frequency domain and obtaining respective samples of the windows of signal in the frequency domain; and mapping the samples in the frequency domain back into the time domain.
