Zusammenfassung:Methods, systems, and apparatuses mitigate a stall condition in an iterative bit flipping decoder. A codeword is received and current bit is selected. In response to detecting the risk of the stall condition and further in response to determining the current bit satisfies the bit flipping criterion, it is determined that the current bit was flipped in a previous iteration. The flipping of the current bit is bypassed in response to determining the current bit was flipped in the previous iteration.
