Abstract
A receiver comprises a demodulator for providing a demodulated signal and a centroid calculator responsive to the demodulated signal for identifying a correct carrier phase for use in the centroid calculation and in removing carrier phase ambiguity in the demodulator. In addition, the centroid calculator may include a limiter.
Claims21
A receiver, comprising:
- a demodulator for providing a demodulated signal;
- and
- a centroid calculator responsive to the demodulated signal for providing a virtual center value for a channel impulse response;
- wherein the centroid calculator is also responsive to the demodulated signal for identifying a correct carrier phase for use in removing carrier phase ambiguity in the demodulator.
1 more element
A method for use in a receiver, the method comprising:
- providing a demodulated signal;
- and
- determining a virtual center for a channel impulse response from the demodulated signal;
- wherein the determining step includes the step of identifying a correct carrier phase for use in removing carrier phase ambiguity in a demodulator.
