用于实现DS-CDMA通信系统仿真的程序 编码transmitter,receriver模块，并对传输信道增加高斯白噪干扰 是通信理论扩频技术的应用实例(Used to implement DS-CDMA communication system simulation program code transmitter, receriver module, and increase the transmission channel is a Gaussian white noise interference spread spectrum communication theory application example)

关于CDMA系统rake接收机的很简单的MATLAB仿真源代码。(Rake receiver on the CDMA system, a simple MATLAB simulation source code.)

说明：  TDFD,双脊金属加载矩形波导，的基模和第一个高阶模的色散曲线计算,TE模的仿真(TDFD,双脊metal loaded rectangular waveguide, the fundamental mode and first higher order mode dispersion curve calculation, TE-mode simulation)

贪婪随机自适应搜索法(GRASP)，使用随机化的最小最小完成时间算法来产生问题的初始解,再通过变邻域下降算法来改进这个解。(Greedy randomized adaptive search method (GRASP), the minimum use of randomized algorithm to generate the minimum completion time of the initial solutions of the problem, and through the variable neighborhood descent algorithm to improve the solution.)

matlab读取心电信号的程序，注意修改数据路径。(The program which is load on the datas of ECG，Please pay attention to the road of the ECG datas。The ECG datas are collect from the MIT center。)

数值分析 通过matlab的实现。由多元插值等程序组成 (matlab numerical simulation)

说明：  《载波相位相对定位双差方程原理》验证 《载波相位相对定位单差方程原理》验证 《载波相位相对定位双差方程原理》验证 《载波相位相对定位双差方程原理》验证当基站离流动站很近，并假设流动站概略坐标等于基站坐标，那么双差方程中距离向量就为0(&quot Double difference carrier phase relative positioning equation theory&quot test &quot single-difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation theory&quot test &quot double difference carrier phase relative positioning equation principle&quot is verified when the base station from the mobile station near, and assuming that mobile station is equal to the base station coordinates approximate coordinates, so double-differential equation from the vector is 0)
