Abstract

In a residue code with the moduli m 1, m 2,…, m n the integer X is represented by the vectorial form { r 1, r 2,…, r n }, such that r i ≡ X mod m i , i = 1,2,…, n. Since the moduli are not pairwise relative primes, not every n-tuple of integers {r i, ¦0 ⩽r i < m i, i = 1,2,…, n} represents a code word: only those satisfying r i = r j mod g ij , where g ij is the greatest common divisor of m i and m j . Thus redundancy is introduced in a distributed way, inherent in the structure of the system. Known theorems on the error detecting, identifying, and correcting capacity of such codes are generalized. Application to brain modeling is touched upon.
