ofdm simulation using matlab

In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

,在MATLAB环境下对 学生自主学习成绩决策表进行了求解,分析了该决策表的上近似集、下近似集、不可分辨关系、约简、核集、属性依赖度的概念,从而 在原始数据的基础上得出了条件属性与决策属性间的关系。 (The knowledge theory based on rough set can help to simplify the knowledge proceeded from originaldata. In the paper it intro- duces the rough set theory and its principle algorithms. MATLAB Rough SetToolbox is programmed to analyze the decision table of self-learn- ing system from students score database.The concepts such as the upper approximation, lower approximation, indiscernibility relation, reduc- tion, core set, and attribute-importance are analyzed based on the score database table.Thus, the relations between condition attributes and de- cision attributes of the score database are obtained on the basis of original data. )
