Abstract
Systems and techniques are disclosed relating to communications. The systems and techniques involve the synchronizing to a signal having a plurality of bits by computing energy for a plurality of different phase offset signal portions, generating a ratio from the signal portion with the highest computed energy and the signal portion with the second highest computed energy, and comparing the ratio to a threshold to determine whether the signal portion with the highest computed energy can be used to determine bit timing.
