MODIFIED MODULUS PROJECTION ALGORITHM FOR ERROR CONTROL IN REDUNDANT RESIDUE NUMBER SYSTEM CODE

Abstract

This paper presents a modified modulus projection algorithm for decoding Redundant Residue Num-ber System (RRNS) codes. RRNS code is maximum-minimum distance block codes. RRNS has found wider applications in the field of signal processing especially for error control. The essence of this modification is to reduce the required computation overhead and speed up operation. The proposed method involves conversion of received residues into mixed radix form. Based on the error detecting capability of RRNS code under study, moduli projection is carried out iteratively to determine the corre-sponding integers. The proposed algorithm considerably reduces the number of required iterations involved in the recovery process, therefore improving the speed of decoding operation.
