Reliability Ratio Based Weighted Bit-Flipping Decoding for LDPC Codes

Guo, F. and Hanzo, L. (2005) Reliability Ratio Based Weighted Bit-Flipping Decoding for LDPC Codes At IEEE VTC'05 Spring, Sweden. 30 May - 01 Jun 2005. , pp. 709-713.

Record type: Conference or Workshop Item (Paper)


In this contribution, a novel reliability-ratio based weighted bit-flipping(RRWBF) algorithm is proposed for decoding Low Density Parity Check (LDPC) codes. The RRWBF algorithm proposed is benchmarked against the conventional weighted bit-flipping (WBF) algorithm [1] and the improved weighted bit-flipping (IWBF) algorithm [2]. More than 1 and 2 dB coding gain was achieved at an BER of 10?5 while invoking the RRWBF algorithm in comparison to the two benchmarking schemes, when communicating over an AWGN and an uncorrelated Rayleigh channel, respectively. Furthermore, the decoding complexity of the proposed RRWBF algorithm is maintained at the same level as that of the conventional WBF algorithm.
