ML frame synchronization for turbo and LDPC codes

This contribution introduces a novel maximumlikelihood (ML) frame synchronization technique for coded systems that exploits the code properties by accepting soft information from the MAP decoder. Simulation results are presented for turbo and LDPC codes, and are compared to performance results of a frame synchronizer that does not use the code properties. We show that code-aided frame synchronization is required for turbo codes and LDPC codes, in order to avoid either very long pilot sequences or a considerable overall BER degradation.
