Abstract :
The digital video broadcasting - second generation terrestrial (DVB-T2) standard has adopted a preamble called P1 symbol to achieve the fast time and frequency synchronization. The P1 symbol also carries basic transmission parameters of DVB-T2 system, such as fast Fourier transform size, guard interval size and transmission type - single input single output or multiple input single output, etc. In this paper, we propose an improved preamble which is modulated by a novel hybrid differential modulation scheme that can provide transmit diversity gain to achieve the same performance of coherent transmission. The proposed preamble has demonstrated a significantly improved signaling error rate performance over various channel conditions compared to the conventional P1 symbol in DVB-T2.
