直线电机simulink建的模型

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)

matlab生成混沌信号的几个代码 以及文档资料 非常好 一次学会混沌信号(matlab to generate a chaotic signal code and documentation is very good chance the chaotic signal)

信号利用QPSK调制，采用全数字化的频偏估计方法(A full digital frequency offset estimation method using QPSK modulation)

RFM 70 radio Transever 2.4GHz

OFDM降低峰平比采用预失真技术，程序仿真了加入预失真技术后的星座图与未加预失真的比较。结果比较明显。采用QAM映射。(OFDM PAPR reducing the use of pre-distortion technology, process simulation technology to join the pre-distortion of the constellation diagram and the following not pre-distortion comparison. More obvious results.)

利用wifi信号进行精准的定位，mit代码(locolizing using wifi)

两机通讯，C语言程序，内详，很好用，接口课程设计(Two-machine communication, C language program, in detail, very good, interface design course)

说明：  程序中比较了NOMA和OFDMA在容量方面，附带一篇论文，讲的比较详细(The program compares noma and OFDMA in terms of capacity, with a paper, more detailed)
