实现在matlab环境下进行参数估计的傻瓜式操作(Implementation in matlab environment parameter estimation operation of a fool)

这是一个matlab图像处理的课件，大概看了一下，还不错，希望能对大家有用。(This is a matlab image processing software, probably looked, well, hoping to be useful for all of us.)

Since the first edition of this book was published seven years ago, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now in wireless systems of a different flavor from the `traditional ones. This second edition represents a substantial revision of the first, partly to accommodate the new applications that have arisen. New chapters include material on modeling and simulation of nonlinear systems, with a complementary section on related measurement techniques, channel modeling and three new case studies a consolidated set of problems is provided at the end of the book.

说明：  此程序基于VV算法的载波相位估计。该算法既可以估计载波初始相位差。这种算法估计的精确度高。(This program is based on the carrier phase estimation of VV algorithm. The algorithm can estimate the initial carrier phase difference. The accuracy of this algorithm is high.)
