说明：  GPS卫星导航信号仿真研究,做导航方向，写matlab仿真程序必备资料，看了肯定不会后悔(Simulation of GPS satellite navigation signals, making navigation directions, the information necessary to write matlab simulation program, certainly will not regret reading)

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.
