USTM

通过具体的信道实例对比几种信道容量，绘出对数正态衰落、瑞利衰落、Nakagami衰落下确定的容量随平均接收信噪比变化的曲线。(The capacity of several channels is compared by a specific channel example, and the curve determined by the logarithmic normal fading, Rayleigh fading and Nakagami fading with the change of the average received signal to noise ratio (SNR) is drawn.)

改进papr，对于改进papr的程序给了完整的代码，具有参考价值(Improved papr, for improving the procedures papr)

三种随机构造法：Gallager_getH、Mackay_getH、PEG_getH(Three random construction methods: Gallager_getH, Mackay_getH, PEG_getH)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

说明：  大规模天线检测，运用近似消息传递算法，仿真实验(Massive MIMO detection by implement AMP)

信号的捕获(直接序列扩频系统的matlab仿真实现，包括M,GOLD序列生成，信道建模，噪声，扩频，解扩)(Signal capture (direct sequence spread spectrum system simulation matlab implementation, including M, GOLD sequence generation, channel modeling, noise, spreading, despreading))

OPNET软件自带的General Tutorial中文译版，学习OPNET非常实用!(OPNET software s own version of Chinese Translation General Tutorial, learning OPNET very useful!)

说明：  点亮led流水灯，通过调用锁相环，可以更改对应的时钟。(Lighting the LED pipelining lamp, the corresponding clock can be changed by calling the phase-locked loop.)

捷联惯性导航与GPS组合导航。采用matlab实现。采用自适应算法对其进行处理。并取得了很好的效果。(Strapdown inertial navigation and GPS Navigation. Using matlab to achieve. Adaptive algorithm used to deal with them. And has achieved good results.)

循环谱估计算法，SSCA，FAM，可以运行，结果不错，你值得拥有(Cyclic spectrum estimation algorithm, SSCA, FAM, you can run, and the results are good, you deserve)
