Abstract A block synchronization data communication system enables data communication to be properly effected even through a transmission channel under an extremely unfavorable conditions as in mobile radio such as automobiles. The block synchronization data communicating system comprises the steps of encoding data to be transmitted and blocking the encoded data, adding a block synchronization signal having a plurality of different successive pattern positioned in the prescribed order to the head of said block data, transmitting the block data added with said block synchronizing signal, receiving said transmitted data and recognizing one of said patterns constituting the block synchronizing signal, estimating the data position based on a block synchronization signal constitution position of the properly recognized pattern, and decoding the block data beginning from said estimated position as received data.
