Data error-detection system and data error-detection method thereof

摘要

The present invention discloses a data error-detection system and the method thereof. The system includes an initializing module, an encoding module, a decoding module and a restoring module. The initializing module arranges the transmitting data in a 3D matrix to produce information data. The encoding module encodes the information data to produce checking data, and outputs encoding data which includes information data and checking data. The decoding module receives encoding data and detects information data according to the checking data to correct the information data and then produces 3D matrix receiving data. The restoring module produces receiving data according to the 3D matrix receiving data. Herewith, the effect of error-detection and correction of the data can be achieved.
