Abstract: In one example, an apparatus includes: a wavelet transform engine to receive a first signal stream and perform a wavelet transform on a first time domain sample of the first signal stream, the first wavelet transform engine to output at least one first coefficient for a first frequency range; an energy calculation circuit to compute a first energy signature for the at least one first coefficient; and a correlation circuit to generate a correlation value using the first energy signature, a second energy signature and a plurality of previous energy signatures.

Abstract: In one embodiment, an apparatus includes first and second tuners to receive and process a radio frequency (RF) signal and output a first and second plurality of frequency domain sub-carriers. The apparatus may further include a combiner circuit to combine a first plurality of demodulated frequency domain sub-carriers and a second plurality of demodulated frequency domain sub-carriers into a plurality of combined frequency domain sub-carriers, and an output circuit coupled to the combiner circuit. In a first mode, the output circuit is to embed a format indicator with each of the plurality of combined frequency domain sub-carriers to indicate a frequency domain format, and to output the plurality of combined frequency domain sub-carriers with the embedded format indicator to a downstream processing circuit for channel decoding.
