Abstract

We present a new algorithm for blind symbol synchronization in orthogonal frequency division multiplexing (OFDM) systems. Unlike the previously proposed algorithms, the new algorithm guarantees correct symbol synchronization, even in the presence of ISI. Also, it does not assume data in an OFDM symbol to be i.i.d. The increased complexity of the algorithm would be acceptable for systems, such as fixed receiver broadcast systems, that require guaranteed synchronization under all conditions
