相控阵天线测试数据的模拟产生与稀疏分解，可用于故障诊断(Phased array antenna simulation test data generation and sparse decomposition can be used for fault diagnosis)

3、 瑞利信道中的调制解调、信道估计： (1) 请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。 (2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与(1)的曲线进行对比。 (3, the Rayleigh channel modulation and demodulation, channel estimation: (1) Please derive the single-path Rayleigh channel coherent demodulation of BPSK BER performance theory, and draw the signal to noise ratio and bit error rate curves. (2) single-path Rayleigh channel, please design a division of the guide-assisted channel estimation method, using Simulink simulation, measurement of the BER performance of BPSK, draw-bit signal to noise ratio and bit error rate curve, and with (1) of the curves were compared. )

mathswork官方出的matlab 鲁棒控制工具箱的用户手册，对搞鲁棒控制的人有帮助。(mathswork official matlab robust control toolbox user manual, help people engage in robust control.)

说明：  对于给定的信号数据，用emd进行信号分解得到固有模态函数imf(implement emd to obtain imfs)

matlab file to get the effect of rayleigh fading

说明：  DSP课程例程： ① 为频率特性加频域容差图； ② 在对数幅频特性上加要求的指标标识； ③ 量化子程序的调用。(DSP courses routines: ① to increase the frequency characteristics of frequency-domain tolerances map ② in logarithmic amplitude-frequency characteristics of the indicators require additional identification ③ quantify subroutine calls.)

说明：  中值滤波 将一幅图片先加载噪声 让后用中值滤波的方法去除(Median filter to add noise to an image after the first use median filter to remove)
