Abstract
Embodiments related to acquisition, detection, and processing of a high-frequency signal are described and depicted.
Claims25
A receiver, comprising:
- a coherent integration stage configured to coherently integrate a signal downconverted using a downconversion frequency, wherein the coherent integration is performed over a first period of integration to produce a pre-detection sample;
- a phase error detection stage configured to produce a phase error signal dependent on a phase error of the pre-detection sample;
- and
- a correction stage configured to output a downconversion frequency adjustment signal in response to the phase error signal.

A receiver comprising a coherent integration stage configured to coherently integrate a received signal over a first period of integration to produce a pre-detection sample, wherein the pre-detection sample is employed to adjust a duration of the first period of integration during acquisition of the received signal.
A method of processing a received signal, the method comprising:
- integrating a signal downconverted by a downconversion frequency over a first period of coherent integration to produce a pre-detection sample;
- producing a phase error signal dependent on a phase error of the pre-detection sample;
- and
- producing a downconversion frequency adjustment signal in response to the phase error signal.
1 more element
A method of processing a signal in a receiver, the method comprising:
- integrating the signal over a first period of coherent integration to produce a pre-detection sample;
- and
- adjusting a duration of the first period of integration during acquisition of the received signal employing the pre-detection sample.
