Abstract

A scheme for determining a flipping energy used in a bit-flipping decoder. The flipping energy is determined based on: a weight of at least one check node coupled to a column; a syndrome as a product of a noisy codeword and a parity check matrix; and a hard decision value of a previous iteration and a channel output value associated with the column.
