This paper describes an efficient, low complexity, a channel decoder with a high capacity, which is suitable for LDPC decoding codes. The implementation details are provided for the decoding algorithm for LDPC-called adaptive threshold bitwise inversion bit (Adaptive Threshold Bit Flipping (ATBF), designed for low implementation complexity and low power operation.
