说明：  高阶累积量进行识别常用的数字调制信号，低信噪比下识别率高达90%(It uses the method of high cumulant to recognize usual digital signals, under low SNR, the radio is still over 90%.)

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)

位同步源代码，是关于MATLAB的，很好的，并且具体有调制解调的功能！(Bit synchronization source code on MATLAB, very good, and the specific modulation and demodulation functions)

捷联惯性导航与GPS组合导航的matlab实现。采用自适应算法来对组合导航时行处理，并取得了很好的效果。

说明：  SOCKET调试工具与压力测试小工具源代码 VS2008下测试通过，非常好用！(SOCKET debugging tools and stress testing tool for source code for VS2008 under a small test, very easy to use!)

高斯加性白噪声信道下polar码的编译码程序，包括各种示例。(AWGN channel under the polar code codec program, including a variety of samples.)
