Abstract
Systems, methods, and circuitries are provided for detecting vital signs based on ultra-wideband (UWB) signals. In one example, a method incudes processing received UWB signals to generate first digital profile data; detecting at least one peak in the first digital profile data; generating a de-spreading template based on the at least one peak; de-spreading the received UWB signal based on the de-spreading template; generating second digital profile data based on the de-spread received UWB signal; and detecting vital signs based on the second digital profile data.
Claims20
An ultra-wideband (UWB) receiver, comprising:
- a first processing path for processing received UWB signals, the first processing path comprising a first analog-to-digital converter (ADC) that generates first digital profile data;
- a second processing path for processing the received UWB signal, the second processing path comprising
- a de-spreading circuitry configured to de-spread the received UWB signal based on a de-spreading template;
- and
- a second ADC that generates second digital profile data based on the de-spread received UWB signal;
- and
- a processor configured to
- detect at least one peak in the first digital profile data;
- and
- generate the de-spreading template based on the at least one peak.
