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

A block synchronization data communication unit in a mobile radio comprising: (1) a transmitting part including: (a) a means for encoding data and forming said data into blocks to be transmitted; (b) a means for adding a block synchronization signal, having a plurality of different successive patterns positioned in a prescribed order, to said data formed into blocks; (c) a circuit means for modulating said data formed into blocks with said block synchronization signal, and (2) a receiving part including: (a) a receiver means for receiving data; (b) a circuit means for demodulating said received data; (c) a means for decoding said demodulated received data; and (d) a means for recognizing one of said patterns constituting said block synchronization signal and for estimating the data position based on a position of said recognized pattern in said plurality of different successive patterns.
