Two-Stage Scattered Pilot Synchronization with Channel Estimation Scattered Pilots Pre-Filling for DVB-T/H
In this paper a two-stage fast scattered pilot synchronization (SPS) scheme is proposed to increase the reliability of scattered pilot synchronization in DVB-T/H. A channel estimation scattered pilots pre-fllling scheme is added to the two-stage fast scattered pilot synchronization scheme and reduces at least one symbol time to the demapping process. By using multi-stage PB-PB (Power-Based) fast scattered pilot synchronization scheme, the performance and reliability is improved with less hardware cost than single stage CB (correlation-based) fast scattered pilot synchronization scheme.
