说明：  无源被动雷达定位中的利用椭圆法求交点，得到目标位置(Passive Radar Detection using Range-Doppler Transformations find ell intersect)

说明：  运用近似熵算法对cpm信号进行调制识别，然后计算识别率。(The approximate entropy algorithm is used to recognize the modulation of CPM signal, and then the recognition rate is calculated.)

西门子STEP7，费斯托阀岛的GSD文件，硬件组态使用(SIEMENS STEP7, GSD File of Fisto Valve Island, Hardware Configuration Use)

说明：  雷达信号分选的经典matlab代码。包含PRI变换、CDIF、SDIF三种方式(radar signal sort include PRI CDIF SDIF)

5G主同步信号m序列根据公式matlab生成(5G Pss m matlab generater)

说明：  实现BPSK的载波同步，采用的方法是锁频环，最大似然法频率估计(BPSK carrier synchronization is realized,the method is frequency - locked loop and maximum likelihood frequency estimation)

RTD2660源码，可以作为参考或者开发之用。(The source of RTD2660.)

PSK通信信号盲解调测试程序，final1_1和final1_2为两种不同的产生PSK通信信号的程序，final2_1预估计载波频率，final2_2预估计码元速率，final3进行载波同步，final4进行码元同步，进而解调出原信号。(PSK Blind Demodulation)

空间无线信道建模程序matlab，考虑了多径延迟，多普勒效应，信号的角度扩展（拉普拉斯分布），MIMO，可以产生MIMO信道矩阵。(Spatial channel modeling procedures matlab, taking into account multi-path delay, Doppler effect, the signal point of view the expansion of (Laplace distribution), MIMO, can generate MIMO channel matrix.)
