Reliability Ratio Weighted Bit Flipping– Sum Product Algorithm for Regular LDPC Codes

In this work, we introduce a novel decoding algorithm named “Reliability Ratio Weighted Bit Flipping–Sum Product” (RRWBFSP) is proposed for regular LDPC codes. “Sum [4] and Flipping” [6] are two separate methods that combined in the new algorithm. The simulations show to exceed Sum-Product algorithms by 0.34 dB. addition, when compared Sum-Product, RRWBFSP approach has about same computational complexity. Thus, codes, of which “Double-Orthogonal Convolutional Recursive” (RCDO) subfamily envisioned use electronic hard disks mobile terminals, can be easily iteratively decoded. This would have impact prolonging life batteries consequently reducing ecological footprint discarded batteries.
