The newly developed 2nd generation standard for digital video broadcasting (DVB-T2) emerges as a significant upgrade over its first generation predecessor DVB-T. The DVB-T2 standard targets an increased system throughput by at least 30% over the DVB-T. This article introduces algorithms in the signal processing chain to improve the mobile operation for DVB-T2. The proposed modified synchronization blocks, along with the improved channel estimation, show significant improvement compared to the results reported in the DVB-T2 implementation guide. In addition, state-of-the-art low-complexity algorithms in the bit processing chain, particularly in the LDPC decoder, are used to provide robustness and support throughput increase, while reducing the implementation complexity. The integrated system is simulated including implementation effects. The simulation results confirm the enhanced performance of the developed integrated model and provide better results compared to those reported in literature.

International audienceA method to design channel interleavers based on span properties and mutual information is presented. Resulting interleavers enjoy better burst error control and can mitigate the effect of regular error patterns. An application example based on the 2nd generation Digital Video Broadcasting Terrestrial (DVB-T2) standard is elaborated. Four channel interleaving structures are generated, resulting from a joint optimization of the interleaver span properties in the time and frequency domains, while guaranteeing good interaction with the bit interleaver. Proposed solutions are compared to the standardized DVB-T2 channel interleaver in terms of performance, latency and complexity. A significant improvement can be observed in severe channel conditions, especially over time and frequency-selective channels with erasures. Moreover, the complexity and latency of the proposed channel interleavers are reduced compared to the original DVB-T2
