调制的代码，包含FSK,ASK等多种调制方式。(Modulation code, including FSK, ASK modulation, etc..)

说明：  通带截止频率 =2 4k rad/s，阻带截止频率 =2 8k rad/s，通带波纹系数 =0.3dB, 阻带波纹系数 =50dB,采样频率fs=20000Hz。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter.)

生成PSK信号。并基于NI的软件无线电平台发送射频信号(PSK signal is generated. And software radio platform based on NI RF signal sent)

单脉冲和差波束测角程序。 此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖(Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan)

说明：  用MATLAB编写UT变换的程序，用于数学计算(UT transform using MATLAB program written for the mathematical calculations)

创建和训练BP神经网络的MATLAB程序设计(Creation and training of BP neural network MATLAB Programming)

利用matlab的m文件，仿真DPSK的差分相干解调法，从发送数据到接收数据，比较完整(Use matlab m files, simulation DPSK differential coherent demodulation method to send data to receive data from a relatively complete)

使用gui编写的计算器功能，与windows上计算器类似(A calculator written in GUI)

本书基于MATLAB 5.2版，提供了使用MATLAB的实践性指导。MATLAB已成为适合多学科、多种工作平台的功能强大、界面友好、语言自然并且开放性强的大型优秀应用软件，同时也已成为国内外高等院校高等数学、数值分析、数字信号处理、自动控制理论以及工程应用等课程的基本教学工具。本书按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；是一本简明的MATLAB参考书，既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所有MATLAB书籍中少有的一大特色。 本书适合作为理工科高等院校研究生、本科生教学用书，也可作为广大科研工程技术人员的自学用书。
