硬判决和和积译码的性能相差不大，而最大似然译码的性能较好。因为最大似然译码的方法是找出所有发送码字中可能性最大的发送码字作为译码估值，是一种通过经验与归纳，由接收值推测发送码字的方法。-Hard decisions and the performance of the sum-product decoding little difference, the maximum likelihood decoding performance is better. Because the maximum

用MATLAB编写代码,在经济和金融中法对连续时间过程实现了封闭的最大似然估计方法-The code, written in MATLAB, implements the closed-form maximum-likelihood estimation method for continuous-time processes in economics and finance. First, the code maximizes the log-likelihood function and d
