解决阵列信号处理中的优化问题，代码很全面，可以直接运行(Solving optimization problems in array signal processing.The code is very comprehensive and can be run directly.)

通过blackman窗进行数据截断后，进行频域去窄带干扰，通过仿真验证正确(Blackman window through the data truncation, the frequency domain to narrowband interference, the right is verified by simulation)

这是瑞利信道中有关多普勒频移的多径信道和单径信道的相关matlab仿真程序,(This is relevant in Rayleigh channel doppler frequency shift of channel multipath channel and a single diameter related matlab simulation program,)

扩展卡尔曼滤波算法(EKF)在电机方面的应用利用扩展卡尔曼滤波器，将转速看成一个状态量，根据定子的电流和电压值估算转速。(Extended Kalman filter algorithm (EKF) the application of the motor)

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.)
