摘要DVB-T2 (digital video broadcasting-second generation terrestrial) system adopted a preamble, with a special C-A-B structure, to accomplish time-frequency synchronization. All existing preamble based synchronization algorithms only utilized the correlation between C and A or B and A, neglecting the conjugate symmetry character within A. By using this character, a new synchronization method was proposed to make detection probability higher and synchronization error smaller. Monto Carlo simulations were carried out in AWGN (addictive white Gaussian noise) channel and TU6 (typical urban) channel with velocity of 30 km/h. Compared with existing synchronization methods, both higher detection probability and smaller mean square error in time-frequency synchronization is achieved. © 2017, Editorial Board of Journal on Communications.
