DEFINITION

Classification: 714/FOR.187

Bose-Chaudhuri-Hocquenghem code:

Foreign art collections including subject matter where the block code is a t error correcting code which is the set of all polynomials [a(c)] over the Galois field GF(2m) of degree n-1 or less, such that a(ai)=0, for i=1,3,5,...,2t-1 where a is a primitive element of the finite field GF(2m), and where c is the radix 2 for binary data, a(c)=a0+a1c+a2c2+...+an-1cn-1, and aj=0,1 (j=0,1,2,..., n-1).
