check bit sum

基本解釋

By simplifying the message sent from check nodes to bit nodes, the complexity of the algorithm approaches that of the "mini-sum" algorithm.
該算法通過(guò)對(duì)校驗(yàn)節(jié)點(diǎn)傳遞給比特節(jié)點(diǎn)的信息進(jìn)行有效簡(jiǎn)化，使計(jì)算復(fù)雜度接近“最小和”算法。
Then it introduces receiving signal as reliability evaluate or weighted coefficient of hard-decision, consequently presents weighted bit-flipping decoding algorithm based on check sum.
在此基礎(chǔ)上引入接收信號(hào)作為可靠性評(píng)估，使評(píng)估值作為硬判決的加權(quán)系數(shù)，從而提出基于校驗(yàn)和的加權(quán)位翻轉(zhuǎn)解碼算法。
