Abstract (en)
[origin: WO0110040A2] Method and device for decoding with error correction of a cyclic code signal r(x) containing a main error burst shorter than or equal to a number n and a secondary error shorter than or equal to a number k where k<n with the secondary burst causing in a syndrome S(x) calculated on r(x) the not zeroing of all the bits in the first n positions with the cyclic code being a shortened Fire code to supply at most a standard correction of a single burst shorter than or equal to n. According to the method the error burst correction algorithm originally proposed by Fire but modified with the error trapping procedure based on recognition of first k bits of the syndrome generated by the secondary bursts is used jointly.
