Correction method of code error

Abstract

Abstract PURPOSE:To execute precise code transmission without making hardware larger and to enhance transmission efficiency by performing automatic correction of errors for small receiving errors, and demanding transmission once for large receiving errors. CONSTITUTION:A receiving code, which is inputted through a receiving circuit 12, is tested for a receiving code error by a remainder arithmetic circuit 41. A divided result of the receiving code is supplied to an error bit number calculating circuit 42, and compared with a threshold of the error bit number. When an error beyond a prescribed bit number is detected, ''1'' is accumulated in a receiving result accumulation circuit 43, and when an error within a prescribed bit number is detected, ''0'' is accumulated. In terms of a communication control device, a communication control circuit 51 reads a receiving result and receives receiving information through a receiving information reading circuit 52 when the receiving result is ''0''. When the receiving result is ''1'', the circuit 52 considers the present receiving not to be conducted; therefore it will not receives information and demands transmission again for the terminal communication control device at an opposite side.
