dc.description.abstractThe Digital Video Broadcasting (DVB) project has developed digital broadcasting system specifications which have been adapted worldwide. The family of DVB standards includes DVB-S for satellite, DVB-C for cable and DVB-T for terrestrial system. This DVB-T system has proven its capability and thus accepted as the standard for terrestrial system in most countries. DVB-T2 is the enhancement of DVB-T that will overcome the shortcomings of the previous standard and provide additional features. This thesis concentrates on synchronization performance in DVB-T2 systems. Synchronization is the most important task that the receiver has to perform in the beginning of its reception of the signal. DVB-T2 uses Orthogonal Frequency Division Multiplexing (OFDM) modulation method and has a special symbol, named P1 symbol, for performing initial synchronization tasks. This symbol is also used for detecting DVB-T2 signal, meaning that, if the receiver can detect the P1 symbol, then it can conclude that the channel contains DVB-T2 signal. Moreover, P1 symbol also transmits basic transmission parameters that the receiver needs in the first place in order to proceed for further processing. In this work, the DVB-T2 system model has been implemented including the P1 symbol and the performance of synchronization by P1 symbol has been analyzed extensively by simulations in different channel conditions. P1 symbol deals with the synchronization issues before performing Fast Fourier Transform (FFT). Therefore, P1 symbol based methods can achieve coarse timing synchronization and fine frequency synchronization. Also the detecting and decoding probabilities based on P1 symbol in different channels are presented in this thesis. /Kir09en
