摘要： Disclosed herein are a 3D TV and a system using RF wireless communication and a method for synchronizing a 3D TV system using the same. In the 3D TV system using the RF wireless communication according to an exemplary embodiment of the present invention, two or more 3D TVs transmit and receive synchronous signals through the RF wireless communication, thereby locking the screen synchronization and synchronous signals of the 3D TVs. Thereafter, when the 3D TVs transmits the synchronous signals to the 3D spectacles, the synchronous signals including the time offset are transmitted, having different time difference. As a result, the 3D spectacles can be synchronized with images displayed on the 3D TVs by using time offset information.

摘要： A timing estimator of an OQPSK demodulator is provided. In the timing estimator, an A/D converter converts an analog reception signal into a digital reception signal. A differential circuit section delays the digital reception signal from the A/D converter by a preset time and obtains a phase difference between a conjugate complex number signal of the delayed digital reception signal and the digital reception signal to offset a frequency error contained in the digital reception signal. A correlation operation section performs a correlation operation between a reference symbol differentiated in the same way as a differentiation of the differential circuit section and the reception signal to obtain each correlation value. A coherent detector detects a coherent point on the basis of the correlation value from the correlation operation section.
