Data communication system with block synchronization data in mobile radio
First Claim
1. A block synchronization data communication method in mobile radio comprising the steps of:
- (1) a step of encoding data to be transmitted and blocking the encoded data,(2) a step of adding a block synchronization signal having a plurality of different successive patterns positioned in a prescribed order to the head of said blocked data,(3) a step of transmitting the blocked data added with said block synchronization signal,(4) a step of receiving said transmitted data and recognizing one of said patterns constituting the block synchronization signal,(5) a step of estimating the data position based on a block synchronization signal constitution position of the recognized pattern, and(6) a step of decoding the blocked data beginning from said estimated position as received data.

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.
