with DVB-T are sensitive to the presence of multipath errors. This paper studies the delay estimation in adverse multipath scenarios using the DVB-T signals. A data-directed delay tracking mechanism is presented for signal tracking to estimate the time delay. Three different delay locked loops (DLLs) are considered to mitigate the

Fig. 7. Ambiguity Function of full DVB-T Signal in 8k-mode operation with a guard interval of 1 4 delay of T U, or 1024 sfor the specified signal. We also note that the power of these peaks is dependent on the length of the guard interval. If the guard interval is longer then more repeated signal contributes to the correlation. If we compare

- correcting audio delay. Sometimes (usually not with the newer methods shown here), audio may be asynchronous. Some DVD authors allow to specify an offset, TMPGenc, e.g., doesn't. In case of mp2 audio we can use a tool named MP3trim, that, unbeknownst to most, also does mp2. If sound is delayed, we open the file with MP3trim, select to cut of frames from the beginning, …

DVB-T Synchronization Needs Transmission of DVB-T signals achieved through SFN requires an overall time and frequency synchronization. Indeed, for each instant of time, every transmitters must broadcast the same digital data at the same exact frequency. The diagram of Figure 1 shows a typical DVB-T network. The video/audio signals with ...
