ABSTRACT:
Methods and systems for detecting bit synchronization boundary in a received signal. A counter is set for defining a bit boundary of the received signal. Transitions in the received signal are detected and compared with the counter value as the transitions are expected to occur only at the bit boundary. The bit boundary is confirmed if a preset number of transitions aligned with the bit boundary.
