In a symbol synchronization apparatus, the period of time required to restore the symbol synchronization lost is minimized. The apparatus includes a receiver for receiving transmission data sent from a transmitter with an error detection code added to each data frame thereof. The receiver includes an error detector for detecting an error in the data frame of the transmission data and producing an error detection signal and a symbol synchronizing unit for receiving the transmission data according to the error detection result, establishing symbol synchronization for the transmission data, and following up the symbol synchronization. When the data frame is free of errors, the symbol synchronizing unit holds sample timing of a last symbol of the data frame and sets the sample timing as an initial value of sample timing of a first symbol of the subsequent data frame. When any error is found in the data frame, the symbol synchronizing unit sets sample timing beforehand held as an initial value of sample timing of a first symbol of the subsequent data frame. |
