说明：  用于MRC的matlab编程仿真，自己觉得好的资料(MISO-NOMA using TAS and MRC)

说明：  对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)

多线程串口编程，程序是使用arm加华为的GPRS模块进行测试 方便大家修改(Multithread serial programming, program is to use the arm GPRS module testing Huawei to facilitate change)

正交频分复用系统中信号的调制与解调，我们用傅里叶反变换和变换来实现(Orthogonal frequency division multiplexing system signal modulation and demodulation, and we use the inverse Fourier transform to achieve transform)

说明：  这是一篇讲述多雷达协同干扰策略和方法的论文，可参考进行相关研究。(This is a paper on the strategy and method of multi-radar cooperative jamming, which can be referred to for relevant research.)

说明：  产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)
