By simplifying the message sent from check nodes to bit nodes, the complexity of the algorithm approaches that of the "mini-sum" algorithm.

该算法通过对校验节点传递给比特节点的信息进行有效简化，使计算复杂度接近“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.

在此基础上引入接收信号作为可靠性评估，使评估值作为硬判决的加权系数，从而提出基于校验和的加权位翻转解码算法。
