In this paper, a new algorithm called Reliability Ratio Weighted Bit Flipping-Sum Product (RRWBFSP) decoding is proposed for low-density parity-check codes. The new algorithm combines two different algorithms, Sum Product [4] and Reliability Ratio Weighted Bit Flipping [6].The results of the simulation show that the new algorithm achieves a 0.34 dB performance gain over of the standard Sum-Product decoding algorithms. Furthermore, RRWBFSP algorithm has almost the same computational complexity compared to the standard Sum-Product algorithm.

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