OFDM系统同步中的定时估计算法，主要使用了极大似然估计法。此程序实现极大似然估计法定时的程序。-OFDM system, synchronization of timing estimation algorithm, the main use of maximum likelihood estimation method. Realize this procedure maximum likelihood estimation when the statutory procedures.

针对两类样本所设计的贝叶斯分类器，包括已知参数和未知参数，当参数未知时，用最大似然法进行参数估计-Bias classifier is designed for two kinds of samples, including known and unknown parameters, when the parameters are unknown, the maximum likelihood method is used to estimate the parameters.
