太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)

FSK modulation and demodulation

说明：  同态滤波使图像亮度较暗的区域变得可见，而高亮区也变得更加清晰，对比度增强，图像可视化程度增加。(homomorphic filtering )

设计一个一维wiener滤波器，并以平稳信号加噪为输入，得到该平稳信号的估计信号，并求出最小均方误差。(Design a one-dimensional wiener filter, and to smooth the input signal plus noise to get the estimated signal of the stationary signal, and find the minimum mean square error.)

说明：  波达方向估计 频率估计 MUSIC 算法 空间角度分辨率有限(DOA)

利用burge算法估计功率谱，并画出不同参数情况下的功率谱曲线。。希望对大家有帮助。(burge algorithm)

基于MATLAB的二进制数字系统的调制(包括2ask_2fsk_2psk_2dpsk)(Based on the the MATLAB binary digital modulation (including 2ask_2fsk_2psk_2dpsk))

这个是pm方程的自适应小波阈值改进,使阈值可以自适应(This is the adaptive wavelet threshold PM equation is improved, which can be adaptive threshold)
