On the analysis of P1 symbol performance for DVB-T2

Abstract

In this paper the second generation digital terrestrial distribution system standardized by the Digital Video Broadcasting Consortium (DVB-T2) is considered and, in particular, we focus on the new structure of the P1 training symbol. Two algorithms making use of this symbol are proposed and analyzed, one for the recovery of the carrier frequency offset, the other for the channel estimation. In particular, their performances are evaluated, theoretically and via simulations, and finally compared to the respective Cramer Rao Lower Bound (CRLB). The results show the two algorithms perform very close to the respective CRLB.
