Synchronization scheme of symbol timing for DoA in digital terrestrial television broadcasting

In this paper, the synchronization method for estimation of direction of arrival (DoA) is proposed. In the proposed scheme, the synchronization evaluation function of the square error between the transfer functions is defined. The evaluation function is minimized. The result is used to compensate the symbol timing error between transfer functions. By using Newton method, it is possible to estimate the symbol timing error less than the sampling interval by using Newton method. The each delay profile can be synchronized and DoA can be obtained well in DTTB system.
