用MATLAB对DSB的调制解调进行仿真模拟，包括时域，频域，加噪，包络。(MATLAB for DSB modulation and demodulation simulation, including time domain, frequency domain, noise, envelope.)

插值滤波器，可以改变样值的抽样速率问题，比如把2倍抽样的样值转换为2.5倍抽样的样值。(Interpolation filter, can change the kind of questions the value of the sampling rate, such as 2 times the sample put the kind of value is converted to 2.5 times the sample value of the sample.)

说明：  此工程用Visual Studio 2019 编写，目的是用来替换Thorlabs公司自己的GUI Kinesis来控制TDC001伺服电机控制器,方便用户自己控制。(This project is written in Visual Studio 2019. The purpose is to replace the GUI kinesis of thorlabs company to control the tdc001 servo motor controller, which is convenient for users to control by themselves.)

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.)

对BPSK进行了仿真，包括模块仿真和程序源代码仿真，我这边可以运行(For BPSK by simulation, including the module source code simulation and simulation)

卫星信道删除卷积码的优化译码算法，介绍打孔卷积码的应用(Satellite channel to remove the convolutional code optimization Decoding Algorithm)

说明：  对NOMA下行链路的用户和信道功率分配的优化(Energy-Efficient Resource Allocation for Downlink Non-Orthogonal Multiple Access (NOMA) Network)
