Abstract:
1. A device for the encoding of information symbols to transmit or to record, and the correcting errors among the symbols received or read, according to codes defined over a Galois field Fq, where q is an integer greater than 2 and equal to a power of a prime number, and in which a set of elements of Fq are considered which are denoted y l (j), where j=1, . . . , R with 1≦R≦q−1 and l=0, . . . , p−1 with p>1, said device comprising: a Reed-Solomon encoder; a Reed-Solomon decoder; a unit serving to calculate the inverse of a Vandermonde matrix; registers A in which there are stored registers S in which there are stored registers Y in which said quantities y
