MATHEMATICAL MODELS OF DISTRIBUTION CHANNELS 畸变信道数学模型。一本介绍畸变信道数学模型的外文书，对通信信道感兴趣的书友，可以看看。很好的一本英文书，一起分享。 (MATHEMATICAL MODELS OF DISTRIBUTION CHANNELS。A book about communication channel ,someone who is interest in DISTRIBUTION CHANNEL must have a look. It is really a good book,share with all of you. )

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.
