用于仿真多普勒频移与每条反射波以及到达角之间的关系,可以自行修改参数得到更多仿真结果,MATLAB2009A上运行通过(For the simulation of Doppler frequency shift and arrival angle of each reflected wave, as well as the relationship between, you can modify the parameters of its own to get more simulation results, MATLAB2009A run through the)

关于泄漏同轴电缆性质，参数的仿真，基于matlab。包括表面波、单模、多模辐射，辐射角，辐射方向图等等。上传者原创程序，专业型很强，非常稀少。(Leakage coaxial cable on the nature of the simulation parameters, based on matlab. Including surface wave, single-mode, multi-mode radiation, the radiation angle, radiation pattern and so on. From original procedure, highly professional, very scarce.)

欧洲标准DVB-S2的LDPC编码的实现代码(European standard DVB-S2 LDPC encoding implementation code)

64QAM调制,采用硬件语言verilog实现,其中调用了DDS的IP核(64QAM modulation, using language verilog hardware implementation, which is called the IP core of the DDS)

说明：  基于次优贝叶斯估计的非线形非高斯条件下的粒子滤波器的MATELAB仿真(based Bayesian estimation of non-linear non-Gaussian under the conditions of the particle filter simulation MATELAB)

用于对基于GOLD码的串行捕获算法，可以自定义信噪比，待捕获信号参数，代码分成搜索跟踪和捕获两部分，其中搜索的步长等参数也可以自定义，代码中acquiresignal.m部分为最终捕获相位展示的主程序。(For the serial acquisition algorithm based on GOLD code, we can customize the signal-to-noise ratio and the parameters of the signal to be captured. The code is divided into search part and capture part, The parameters such as search step can also be customized. Acquiresignal.m part is the main progress to output the results of the capture of phase.)
