Frequency Offset Estimation Algorithm Based on DVB-T2 System

This paper starts from the structural characteristics of preamble P1 formulated by The Second Generation Digital Terrestrial Television Broadcasting System (DVB-T2) standard. Through the derivation and calculation of the internal symmetry relationship of P1, combined with the fixed frequency offset characteristics of P1, a frequency offset estimation algorithm is proposed. Through 1000 simulation experiments and result analysis, it shows that the algorithm can greatly improve the frequency offset estimation accuracy of DVB-T2 system.
