Abstract
An example apparatus includes: channel frequency response (CFR) circuitry configured to: receive communication signals; and determine magnitudes of the communication signals; and quality metric circuitry coupled to the CFR circuitry and configured to: determine a quality metric using the magnitudes of the communication signals; select one of a first distance estimation model or a second distance estimation model using the quality metric; and estimate a distance using characteristics of the communication signals and the selected distance estimation model.
Claims20
An apparatus comprising:
- channel frequency response (CFR) circuitry configured to:
- receive communication signals;
- and
- determine magnitudes of the communication signals;
- and
- quality metric circuitry coupled to the CFR circuitry and configured to:
- determine a quality metric using the magnitudes of the communication signals;
- select one of a first distance estimation model or a second distance estimation model using the quality metric;
- and
- estimate a distance using characteristics of the communication signals and the selected distance estimation model.
A method comprising:
- determining magnitudes of communication signals;
- determining a quality metric using the magnitudes of the communication signals;
- selecting one of a first distance estimation model or a second distance estimation model using the quality metric;
- and
- estimating a distance using characteristics of the communication signals and the selected distance estimation model.
At least one non-transitory computer readable storage medium comprising instructions that, when executed, cause programmable circuitry to at least:
- determine magnitudes of communication signals;
- determine a quality metric using the magnitudes of the communication signals;
- and
- select one of a first distance estimation model or a second distance estimation model using the quality metric to estimate a distance;
- and
- estimate a distance using characteristics of the communication signals and the selected distance estimation model.
