本文详细描述了利用三元一参法客观评估学生学习状况，并用灰色理论对学生成绩走向进行预测，可行性极强。 欢迎广大算法爱好者对次评估系统进行改进，同时也希望从事教育行业并且对数学算法有一定了解的朋友们，可以将此模型应用于初中及高中学生。此模型获得东北三省数学建模联赛二等奖。算法使用Matlab实现，部分给出。 (This paper describes the use of objective assessment of the Act Three students in a learning situation, and using gray theory to predict the direction of student achievement, feasibility strong. Welcome fans of the sub-evaluation system algorithm to improve, but also want to engage in the education sector and have some understanding of mathematical algorithms friends, this model can be applied to middle and high school students. This model of mathematical modeling to obtain Northeast League Award. Algorithm using the Matlab implementation, part of the given.)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)
