ABSTRACT:
Briefly, in accordance with one embodiment of the invention, a coarse frequency burst detector for use at the receiving end of a wireline communications system comprises: a digital signal filter adapted to filter a component of decoded signal samples, the decoded signal samples being derived from a baseband signal transmitted via the wireline communications system; and a threshold detector adapted to threshold the signal level of the filtered component of the decoded signal samples with respect to a substantially predetermined level. In accordance with another embodiment, a method of detecting at the receiving end of a wireline communications system a frequency burst in a baseband signal transmitted via the wireline communications system comprises the steps of: filtering a component of a decoded signal derived from the baseband signal transmitted via the wireline communications system; and thresholding the filtered component.
