Patent Searching and Data


Title:
ERROR CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH0730436
Kind Code:
A
Abstract:

PURPOSE: To eliminate the necessity of rereceiving or rereading processing by using the data of a received word as correct data when the number of errors generated only in an error correction code or error detection code inspecting symbol is a value within an allowable range.

CONSTITUTION: An error control system using a code obtained by combining an error correction code 2 and an error detection code 3 with a data part 1 is used. At the time of judging that errors less than the allowable number of errors exist only in an error correcting inspection symbol or an error detecting inspection symbol based upon a correction state at the time of decoding the code 2 or the decoded state of the code 3 in this error control system, the decoded result of the data part 1 in a received word is accepted as a correct result. Thereby a trouble causing the disablement of the data part 1 due to errors generated only in the error correcting inspection symbol or the error detecting inspection symbol can be solved and highly efficient error control capable of suppressing rereceiving or rereading processing to its minimum required can be executed.
