Abstract
Aspects of this disclosure relate to determining a spectrum mode of a Convergent Digital Radio signal. The Convergent Digital Radio signal can be filtered by a plurality of filters. Correlation coefficients can be generated from filtered signals, in which each correlation coefficient corresponds to a particular spectrum mode. The spectrum mode can be selected based on the correlation coefficients.

(canceled)
Signal processing circuitry comprising:
- a plurality of filters including a first filter and a second filter, the first filter having a passband corresponding to a first spectrum mode, and the second filter having a passband corresponding to a second spectrum mode;
- a plurality of correlators configured to generate correlation coefficients, the plurality of correlators being coupled to the plurality of filters;
- and
- a selection circuit configured to determine a spectrum mode of a Convergent Digital Radio signal based on at least two of the correlation coefficients from the plurality of correlators.
