Describe the principles of synchronization in systems of digital television broadcasting DVB-T2 and TDS-OFDM (DTTB), which provide all forms of synchronization with the signal analysis in time and frequency domains. In the system TDS-OFDM guard interval to obtain the pseudo-random sequence – m-sequence, which is used for synchronization and estimation of channel state. It allows to provide high interference immunity of the system and the acceleration of the synchronization process. It is
