Title: Method and device for decoding bch code
Inventor: KIMURA TOMOHIRO
IPC: H03M13/15
Filed: 1989-12-08
Abstract: PURPOSE:To form a decoder of BCH code with only a logic circuit element by finding syndromes at two syndrome generation circuits, respectively, and obtaining an error correction signal by performing the arithmetic processing of those syndromes on a finite field. CONSTITUTION:A code system encoded with the BCH code capable of performing error correction for bits less than two is set as input, and first and second syndromes S1, S3 are found from the above code system at the two syndrome generation circuits 1, 2 based on first and second inspection matrices of BCH code. Then, a first inspection code P1 is found by performing power multiplication on the syndrome in which a constant is subtracted from the syndrome S1 on the finite field. Also, a second inspection code P3 is found by subtracting the constant from the syndrome S3 on the finite field. When the code P1 coincides with the code P3 and at least one bit of bit strings of the syndrome S1 is not zero, error correction information can be obtained, and the above code system is inverted according to the error correction information. Thereby, it is possible to obtain a decoding system in which an error included in the code system is corrected.
