Abstract

PURPOSE:To utilize a transmission circuit efficiently and to form a highly reliable transmission system by stopping resending operation resulting from a transmission error at a proper frequency and by generating information to be deemed as real received information. CONSTITUTION:A0, A1...AM-1 are received erroneous pieces of information when random transmission errors regarding original information A to be sent are detected and resending is repeated up to M-1 times and C0, C1...CM-1 are error check codes for respective times when the check code of the original information A is C. To generate information MA as real received one from them, the frequency of ''1''s and that of ''0''s are counted first with respect to each of (n) bits and their difference is found; when the difference is greater than a preset value, the ''1'' or ''0'' greater in the number of bits is employed. Then, this operation is carried out with regard to (n) bits and the information AM as real received one at the point in time is thus generated.
