Relay transmission system and method thereof

PURPOSE: A relay transmission system and method thereof are provided to improve the efficiency of a repeater system by reducing power consumption rates of a repeater. CONSTITUTION: A transmission apparatus(100) transmits fragment data by simplifying transmission data based on a data distribution method. Repeaters(210~230) receive the fragment data allocated from the fragment data. When the fragment data is received, a reception apparatus(300) restores the transmission data based on sequence information included in the fragment data. The sequence information is added to the transmission data by establishing compression sampling data and the number of the repeaters, and by dividing the fragment data.
