Abstract :
We present a maximum likelihood (ML) frame synchronizer for OFDM systems. The synchronizer exploits a synchronization word and cyclic prefixes together to improve the synchronization performance. The frame synchronizer problem is defined as a maximum a posteriori probability estimation. Numerical results showed that the performance of the proposed frame synchronizer is better than that of conventional synchronizers.
