Title: Error correction receiver
Inventor: KONISHI TAISUKE
IPC: H03M13/19
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To solve a problem that errors of two or move bits cannot be corrected in a conventional error correction receiver receiving a Hamming- encoded signal since a Hamming code is a one bit error correction code. SOLUTION: An error correction receiver is provided with a synchronism detection means which receives a Hamming-encoded signal on a transmission side and synchronously detects a reception signal, a judgement means for judging the signal of the output of the synchronism detection means by a prescribed threshold, a differential decoding means for obtaining the change of the output of the judgement means for one symbol, a division means for dividing the output of the differential decoding means by a prescribed generated polynomial and obtaining a remainder and an error correction means which corrects the error of the output of the differential decoding means in accordance with the value of the remainder being the output of the division means, and the receiver receives Hamming-encoded signals.  Even if continuous two bits are erroneous, the error can be corrected by a Hamming code being a one bit error correction code.
