Error Performance of Hybrid Weighted Bit Flipping decoder for Security Applications using EG-LDPC codes

Abstract

Abstract— Low Density Parity Check codes are deciphered by iterative data passing calculations, which can accomplish magnificent execution. LDPC codes are decrypted by using hard decision, Soft decision or cross breed deciphering plans. LDPC codes are the type of linear block LDPC codes. The designation originates after the normal for their equality check grid which contains just a couple of ones in contrast with the number of measured zeros. These LDPC codes primary leverage is that they stretch an execution which is near the limit with regards to a variety of channels and straight time complex calculations for deciphering. In this paper, a half and half weighted piece flipping deciphering calculation for low-thickness equality check codes is proposed. BF is straightforward and simple to be actualized, however has just restricted unravelling execution. The Hybrid Weighted BF (HWBF) calculation utilizes both the check connections and the dependability of get message, thusly acquires a superior unravelling execution when contrasted to BF calculation. Hybrid Weighted Bit Flipping (HWBF) offers a decent trade-off between execution, unpredictability and speed. The primary favourable position of HWBF is the way that at every emphasis, weighted wholes of similar qualities are processed. Thus these entities can be pre-processed, so the speed preferences of BF are safeguarded.
