In this paper we propose a novel timing and frequency synchronization and decoding method for the P1 symbol in DVB-T2 based on the correlation between the received signal and the time domain P1 symbols. This method does not require post-FFT decoding and is insensitive to the frequency-shift offset and continuous-wave (CW) interference. The performance of the proposed method is evaluated via computer simulations, which shows that not only does it achieve good synchronization performance, but also it provides a decoding SNR gain of at least 6dB in AWGN channel and at least 2dB in multipath Rayleigh fading channel compared with the performance reported in the standard guidelines.
