Abstract
A method for locating an end of a received frame includes providing hypothetical trellis paths that end at different possible end points, performing a CRC check for each hypothetical trellis path, calculating a false detection variable for hypothetical trellis paths that passed the CRC check, and determining the end point of the received frame in response to the calculations.
Claims24
A method for locating an end of a received frame, the method comprising:
- providing at a processor device hypothetical trellis paths that end at different possible end points;
- performing at the processor device, for each hypothetical trellis path, a forward detection check;
- calculating at the processor device a false detection variable for hypothetical trellis paths that passed the forward detection check, wherein a calculation of the forward detection check is faster than a calculation of the false detection variable;
- and
- determining at the processor device the end point of the received frame in response to the calculations.
