风干扰下弹道解算程序Trajectory-Program

对ofdm不同cp长度下系统性能的分析(Performance analysis of OFDM systems with different CP lengths)

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)

说明：  一个简单的verlog HDL教程，内容比较详细，可读性较高。(A simple verlog HDL tutorial, more detailed content, high readability.)

使用周期图法进行谱估计，主要使用自相关算法和直接法(We use the periodogram method to estimate the spectrum, mainly using autocorrelation algorithm and direct method.)

针对GPS干扰特性，对GPS系统进行猛特卡落干扰仿真(GPS interference characteristics for the GPS system Meng tecka charged interference simulation)

说明：  Labview OPC和欧姆龙PLC通讯(LabVIEW OPC and OMRON PLC communication)

残疾人代码，手机定位，一键呼救应用程序，对残疾人的生活起到了很大的作用(Disabled code, mobile positioning, a key application for help)

关于移动通信中MIMO中的CDD发射分集算法( CDD transmit diversity algorithm on MIMO in the Mobile communication)

说明：  用于iOS平台的 ping demo,对苹果原生代码的封装(use for iOS partform ping demo)
