说明：  频分复用信号的生成以及演示，与英文工具书匹配，很好用！(FDM signal generation)

GPS 软件接收机，using sp3,计算采用FFT算算法，长度为65536，捕获C/A码(Welcome to our software receiver Using sp3 file for navigation information. precalculating C/A code FFT tables...acq buf len = 65536)

主要是在fluent里或者在其他软件里 添加测点文件的编程(Mainly in fluent or in other software to add test point file programming.)

说明：  大规模MIMO中采用天线选择来降低系统复杂度和成本，其中包括最优天线选择和递减天线选择，快速天线选择和基于范数的天线选择算法。(Antenna selection is used in large-scale MIMO to reduce system complexity and cost, including optimal antenna selection and decreasing antenna selection, fast antenna selection and antenna selection algorithm based on norm.)

Matlab里面没有提供直接以半径和圆心位置画圆的程序，该程序可以实现此功能，命令格式为：circle(radius,x0,y0, color )(Matlab which does not provide the location directly in the center circle radius and the program, the program can achieve this functionality, the command format is: circle (radius, x0, y0, color ))

说明：  用于FDD网络的D2D联合资源分配，matlab仿真程序。(D2D joint resource allocation for FDD network, matlab simulation program.)

一种基于LFM和Barker码复合调制的雷达波形，理论上分析了该低截获雷达波形的组成。通过仿真得到复合调制信号的时域波形、频谱图和模糊函数图，与LFM信号和Barker码信号对比分析对复合调制雷达信号的距离和多普勒模糊函数、截获因子等进行了研究。(A radar waveform based on LFM and Barker code modulation is presented. The composition of the waveform is analyzed theoretically. The time domain waveform, spectrum and ambiguity function of the compound modulation signal are obtained by simulation. The range and Doppler ambiguity function and interception factor of the compound modulation radar signal are studied by comparing with LFM signal and Barker code signal.)

说明：  最基础的检测概率；虚警概率；漏检概率与门限的关系。(Energy detection;Single threshold.)
