Abstract
A method and system for detecting an end of a preamble without interpolation. The method includes receiving information from a zero phase start module, the information including a target phase constraint, a polyant, and a zero phase start phase. The method also includes selecting two samples per preamble cycle of short filter outputs and long filter outputs based on the target phase constraint, the polyant, and the zero phase start phase. The method further includes decimating the short filter outputs and the long filter outputs such that the selected two samples for each of the filters per preamble cycle are output upon decimation. The method additionally includes performing a sign comparison on the corresponding short filter and long filter outputs after decimation, wherein a sign mismatch of the corresponding short filter and long filter outputs indicates an end of a preamble.
