<p>PROBLEM TO BE SOLVED: To obtain the ATM transfer error correction device in which a multi- value reception signal is simplified into a ternary value, and the ternary value is processed into a pattern so as to attain pattern matching with a small calculation amount and a conventional DSP is used for economical configuration. SOLUTION: A multi-value reception signal (r) is simplified into a ternary value by a ternary threshold level decision means 1, the reception signal subject to ternary processing is patternprocessed by a ternary pattern processing means 2, a processing object data amount is reduced and a proportional pattern matching executing a small calculation amount is conducted to decide a reproduction position. A reproduction means 6 reads a reception signal stored in a reception signal storage means 5 according to the reproduction position obtained by the ternary pattern matching means 4 and the reception signal is sent in place of a reception signal with an ATM transfer error.</p> |
