Abstract :
This paper introduces an optimum maximum a posteriori (MAP) frame synchronization method for packet-based turbo coded communication systems. The synchronizer maximizes the probability of frame synchronization by observing the received signal sequences. This method is based on the low-density parity-check properties of turbo codes and does not require insertion of sync words or preambles.
