Abstract
A time synchronisation method without specific symbols for an orthogonal frequency division multiplexing (OFDM) system is investigated. The coarse time synchronisation and the fine time synchronisation algorithms are described. The problem of the time synchronisation of a coded OFDM terrestrial digital video broadcasting receiver in the presence of long echoes and pre-echoes is then analysed and worked out by an optimum use of both algorithms, which prove complementary
