Abstract
A device for detecting a timing synchronization, a method, and a communication device. The device includes a unit for outputting a timing synchronization discriminating signal, which corresponds to a difference between samples that are ahead and behind of the input signal by a semi-symbol period; a unit for semi-symbol delaying a real number element and an imaginary number element of the input signal, and subtracting the delayed signals from the real number element and the imaginary number element of the input signal; a first detector for detecting a power from the semi-symbol delayed signals of the input signal; a power detector for detecting a power from the real number element and the imaginary number element from the timing error detecting unit; and a subtracter for subtracting a value, which is obtained by multiplying the power detected by the second detector by a predetermined coefficient, from the power detected by the first detector.
