Abstract

Abstract:- Normally decoding is done to correct errors present in the codeword by calculating syndrome. syndrome calculation for large size codeword makes decoding more complex. This paper presents an error detection and correction schemes using Majority Logic Decoding(MLD) which provides simple decoding process to detect and correct errors, the existing MLD requires number of clock cycles equal to size of codeword to detect error but the proposed decoding significantly reduces the iterations by detecting error within three clock cycles for any size of codeword using control logic.Also the proposed scheme uses detection logic to detect the uncorrectable codeword if error occured is more than actual capacity of system. Hence this makes error detection and correction schemes more efficient. Keywords:- Block codes, Error correction codes(ECCs),LowDensity Parity Check(LDPC),Majority logic Memory., I.
