摘要： An apparatus and method for detecting synchronization and signals using block data processing in a receiving system are provided. To process an input signal, a cumulative matrix is obtained from an input vector signal for each frame generated from the signal. A primary eigenvector is extracted from the cumulative matrix, and the maximum value of a correlation vector is calculated from the extracted primary eigenvector. A time delay is detected by comparing the calculated maximum value of the correlation vector with a first threshold value, and a delay correlation vector is calculated from the detected time delay. Finally, synchronization and signals are detected by comparing the calculated delay correlation vector with a second threshold value.
