Abstract
In this paper, we proposed new fast scattered pilot synchronization techniques to reduce the burst synchronization time for the DVB-H receiving system with robustness. DVB-H terminals employ a TDM system called 'Time-Slicing' to reduce power consumption. In order to fully exploit the potential power reduction, the synchronization time for the DVB-H receiver must be very short. A typical DVB-T system uses the TPS Synchronization to determine the position of scattered pilots which are used for channel estimation, and it takes 68 OFDM symbol time. In this paper, several new fast scattered pilot synchronization techniques are proposed.
