A symbol timing recovery apparatus usable with a VSB receiver, includes a first correlator to calculate a first correlation value between an I channel receiving signal and a timing recovery reference signal, a second correlator to calculate a second correlation value between a Q channel receiving signal having a phase difference of 90° with respect to the I channel receiving signal and the reference signal, a calculating member to calculate a non-coherent combining value based on the first correlation value output from the first correlator and the second correlation value output from the second correlator, an early-late subtractor to calculate a difference value between the non-coherent combing value of a previous sample and the non-coherent combing value of a subsequent sample in samples of the I and Q channel receiving signals, and to detect a symbol timing offset based on the calculated difference signal, and a symbol timing controller to control symbol timing based on the detected symbol timing offset. Accordingly, by using the non-coherent combining value of the first and second correlation values, it is possible to perform the symbol timing recovery regardless of carrier recovery error, thereby minimizing symbol timing jitter.
