ofdm仿真程序有关信道传输中的多径效应，多普勒频移，时延扩展(OFDM simulation program on the transmission channel of multi-path effects, Doppler frequency shift, delay spread)

说明：  实现DSP28335内的SCI通信程序，经过测试后可以使用(Implement the SCI communication program in DSP28335, which can be used after testing)

基于dsp的信号四路输入检测，非常实用，值得你们下载哦(Four based on the signal input detection dsp and very practical, it is worth your download Oh)

利用锁相环来实现MSK信号的定时同步，采用的是gardner算法(Using phase-locked loop to achieve timing synchronization of MSK signal, Gardner algorithm is adopted.)

GPS的CA码产生过程，对CA码进行bpsk调制后得到一个GPS中频信号，画出其时域和频域图(GPS-CA code generation process, the CA code bpsk modulated IF signal of a GPS, to draw the time-domain and frequency domain Figure)

根据卫星的位置和速度，求取实时卫星轨道的两行根数，即6个开普勒根数。计算结果精度很高。(The position and velocity of the satellite strike two lines of the real-time satellite orbit root number, six Kepler root number. Calculation results of high precision.)

说明：  使用LS算法对OFDM的信道进行估计，该算法估计行道计算量小，但是容易受到噪声的影响。(The OFDM algorithm is used to estimate the channel of OFDM. The algorithm estimates that the calculation amount of the road is small, but is susceptible to noise.)

说明：  详细的OFDM设计过程，包括Matlab仿真、DSP源码及文档说明。 OFDM(正交频分复用)技术实际上是MCM(Multi-Carrier Modulation，多载波调制)的一种。(OFDM detailed design process, including the Matlab simulation, DSP source code and documentation. OFDM (Orthogonal Frequency Division Multiplexing) technology is actually MCM (Multi-Carrier Modulation, multi-carrier modulation) is.)

说明：  顶帽变换的程序，能够实现平滑图像的效果。(Cap transformation process, to achieve the effect of smoothing the image.)

涉及12种copula的估计，以及模型的比较(Estimates of 12 kinds of copula, and comparison of the models)
