Abstract:
Disclosed is a symbol timing determining device including: a symbol timing detecting circuit detecting a reception signal to obtain a first symbol timing, and shifting the first symbol timing to obtain a second symbol timing; an estimation signal generating circuit processing the reception signal according to the first and the second symbol timings respectively, so as to obtain a first and a second channel estimation frequency-domain signals; a channel estimation impulse response signal generating circuit generating a first and a second channel estimation impulse response time-domain signals according to the first and the second channel estimation frequency-domain signals respectively; a power measuring circuit measuring the energy of the first and the second channel estimation impulse response time-domain signals according to a predetermined signal region respectively; and a decision circuit selecting one of the first and the second symbol timings according to a relation of the measured energy.
