改程序为应用M语言实现对FDMA系统的设计仿真，包括发送接收端以及用户端的仿真(The program is designed to simulate the FDMA system by using M language, including sending and receiving terminal and user side simulation.)

说明：  LED样例代码，原厂提供。凑够20个字才行吗？(Led sample code, provided by the original factory. Can you make up 20 words?)

说明：  基于MUSIC算法，能够实现任意线阵的到达角估计，并分析信噪比等因素对估角精度的影响。(Based on music algorithm, DOA estimation of any linear array can be realized.)

Millimeter-wave Beamforming and Phased Arrays

说明：  面阵中的DOA估计，利用ESPRIT进行估计(DOA estimation in plane array is performed by ESPRIT)

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.)

基于esprit算法的宽带信号（线性调频信号）doa估计(DOA estimation based on esprit)

包括turbo，polar，LDPC信道编码，交织，QAM，SCMA，MIMO检测，译码等(Including turbo, polar, LDPC, channel coding, interleaving, QAM, SCMA, MIMO detection, decoding, etc.)

基于.net开发的opcClient，可连接OPC服务器，检测OPC服务器信号值的变动(Connection detection OPC server)

说明：  对铭泰读卡器不同扇区进行读写操作，初始化扇区，扇区信息加密。(Reading and Writing Mingtai Card Reader)
