Nakagami信道仿真，看后能够用三种方法仿真出Nakagami信道~可以向我要源代码(Nakagami channel simulation, three ways to look after the simulation the Nakagami channel ~ I want the source code can)

基于MATLAB的OFDM系统仿真及分析（16QAM调制后星座图 OFDM载波幅度谱，相位谱，OFDM时域和频域分析 加窗后OFDM频谱分析 循环前缀对星座点的影响 ） (ofdm )

AX.25业余无线电数据通信协议通信的实现程序，包括打包和解包。(A program for packeting and unpacking AX.25 protocol.)

16QAM数字基带信号系统仿真，包括发射机程序和接收端程序(16QAM digital baseband signal system simulation)

说明：  读取SHT20的数据发送到主控STM32F103vet6(Read data from SHT20 and send it to master STM32F103vet6)

说明：  利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)

用于通信方向中的信道估计，使用的语言是matlab(Used for channel estimation in the communication direction, the language used is matlab)

说明：  简单实现基于加权分数傅里叶变换的混合载波系统(Simple Implementation of Hybrid Carrier System Based on Weighted Fractional Fourier Transform)

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)
