1. A method, comprising:

  • receiving a signal, the signal encoding a data packet;

    sampling the signal to generate sampled values;

    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 comprising a first reference function and the second reference template comprising a second reference function in quadrature with the first reference function;

    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.
