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.
該算法通過對校騐節(jié)點傳遞給比特節(jié)點的信息進行有傚簡化，使計算複襍度接近“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)上引入接收信號作爲(wèi)可靠性評估，使評估值作爲(wèi)硬判決的加權(quán)系數(shù)，從而提出基於校騐和的加權(quán)位繙轉(zhuǎn)解碼算法。
