SUMMARY
Low-density parity-check (LDPC) codes are powerful error correction codes that achieve performance near the Shannon limit with low decoding complexity. While the BP decoder exhibits excellent performance, this state-of-the-art algorithm requires complex computations in variable and check nodes. Bit flipping (BF) is the simplest iterative decoding algorithm that operates with one-bit messages and can provide very high throughputs when only hard decisions are available at the channel output. The BF algorithm has lower complexity when compared with the simplest hard-decision message-passing algorithm (GallagerB), as there is . . .
