This paper introduces a new technology of error correction with the capability of self-detecting and correcting during information transmission and put forward the technology of n-k code error control. That is, add c bits monitoring codes at the sending end to the k bits information. The receiving end according to the fixed regulation examines information codes during transmission to detecting errors and correcting them. The tests of realized chips of error correction show that this technology is a big success in automatically correcting single error code during the transmission of information.
