Patent GB-1224423-A (GB)
Title: Improvements in or relating to error correcting
IPC: H03M13/17
Filed: 1969-01-23
Abstract: 1,224,423. Error-correcting circuits. CODEX CORP. 23 Jan., 1969 [7 Feb., 1968], No. 3748/69. Heading G4A. An error-correcting circuit can correct error bursts up to length (N - K)/2 in an N-bit word containing K information bits. From the N- bit word an N-bit syndrome is calculated. If the N-bit word contains a b-bit error burst the syndrome contains a (b + K) -bit error burst, other bits in the syndrome being zero. The position of the longest O-bit run in the syndrome is determined and the syndrome used to correct the error burst. In the embodiment described N=63 and K=45, the received 63-bit word is placed in register 20. During a first pass the bits are read out serially via switch 50 to 18-bit register 52 and are also returned to register 20. Various of the stages of register 52 are interconnected via modulo-2 adders as shown, resulting in the generation of the 63-bit syndrome. After K=45 bits have been read from register 20, and during a second pass in which the word in register 20 is recirculated and switch 20 is opened, a counter system C 1 , C 2  determines the longest run of O-bits in the syndrome. Counter C 1  determines the run length of the first O-bit sequence. At the end of the first run the counter's contents are set up on a second counter C 2 . Counter C 2  is counted down by the second O-bit sequence and if it does not reach zero C 2  is reset to the state of C 1 . If C 2  does reach zero subsequent 0-bits in the second sequence advance C 1 . This process repeats for each O-bit sequence (other than for any such sequence wholly contained between bits 45 and 62) so that at the end of the second pass C 1  shows the length of the longest O-bit sequence. During a third pass the point in the syndrome at which the longest O-bit sequence ends is determined by a generally similar operation of C 1 , C 2 , this point being the start of the error burst. Gate 133 is fed with the received 63-bit word from register 20 during pass 3, the other input being zero until the start of the error burst, whereupon switch 140 is closed. Consequently each subsequent bit from register 20 is inverted if the corresponding syndrome bit is a 1-bit, the corrected word appearing at the output of gate 133.
