Abstract
A method may include receiving a signal. The signal may encode a data packet. The method may include further sampling the signal to generate sampled values, and generating a slice record comprising a plurality of slices from the sampled values by correlating the sampled values with first and second reference templates. The first reference template may include a first reference function, and the second reference template may include a second reference function in quadrature with the first reference function. The method may further include cross-correlating the slice record with a stored template to generate cross-correlation terms, and determining when a magnitude of the cross-correlation terms exceeds a predetermined threshold for a width of the stored template.
