1、Rayleigh_Doppler_singlePath.m 产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法； 2、Rayleigh_Doppler_multiPath.m 根据多条径的延时和强度，产生频率选择性衰落； 在单径和多径两个程序中，均提供了其功率谱的输出代码； (1, Rayleigh_Doppler_singlePath.m Single Path Rayleigh fading generated using the six kinds of methods and compared recommend using the first six kinds of methods 2, Rayleigh_Doppler_multiPath.m Drive under a number of delay and intensity, resulting in frequency selective fading in single-track and multi-path two procedures, which provide the power spectrum of the output code )

说明：  本程序用于完成BPSK、QPSK、pi/4QPSK、OQPSK、8PSK、16QAM、32QAM、64QAM和128QAM的调制仿真。并可任意扩展到MPSK和MQAM。程序分成四个部分，fir.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； modal.m 为主程序，完成岁各种信号的基带星座图映射、脉冲成型和调制；pi4QPSK.m 为pi/4QPSK信号的星座图映射程序；test1.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, pi/4QPSK, OQPSK, 8PSK, 16QAM, 32QAM, 64QAM and the modulation 128QAM simulation. Arbitrary and may be extended to MPSK and MQAM. Procedures are divided into four parts, fir.m of baseband symbol pulse sequences forming, optional rectangular pulse, raised cosine square root raised cosine pulse and pulse modal.m-based procedures, the completion of the age range of the base-band signal constellation diagram mapping, pulse shaping and modulation pi4QPSK.m for pi/4QPSK signal constellation diagram mapping procedures test1.m given spectrum shows a simple test.)

The book is divided into three parts: theory, method and implementation. Starting with a summary of the state-of-the-art in mobile technologies, the first part analyses their impacts on cartography and pinpoints the missing theories concerned with the development of map-based mobile services. A conceptual framework of mobile cartography is then introduced with the emphasis on mobile usage context. The second part is devoted to the design methodology under the constraints defined in the theoretical framework. A core issue deals with personalised mobile map services. The final part demonstrates the feasibility of the methods by using application scenarios.

Here is a lumped parameter model of a hydraulic transmission line. The line is modeled by one, two, three, four and ten lump models. The simulation program presents the transient response in addition to experimental results.
