1. A method of decreasing false detection of wake-up patterns of a receiver, comprising:
- receiving a protocol in the receiver, wherein the protocol includes non-biphase encoded information having a plurality of bit lengths;
decoding the protocol using a biphase decoder to produce a detected code; and
correlating the detected code with a known code to verify the non-biphase encoded information.
