代码说明:

  利用Matlab软件编程实现DDS(直接数字频率合成技术)。设时钟的频率为固定值f_C,在CLK的作用下,如果按照0000,0001,0010,…,1111的地址顺序读出ROM中的数据,即表1中的幅值编码,其正弦信号频率为f_01;如果每隔一个地址读一次数据(即按0000,0001,0100,…,1110顺序),其输出信号频率为f_02,且f_02将比f_01提高一倍,即f_02=2f_01;其余类推。这样,就可以实现直接数字频率合成器的输出频率的调节。(Matlab software programming DDS (direct digital frequency synthesis). Clock frequency set to a fixed value f_C, under the effect of CLK, according to 0000,, ..., 1111 of the sequence of addresses in the ROM reads the data, i.e., the amplitude of the encoding in Table 1, the frequency of the sinusoidal signal f_01 if every time a read address data (ie 0000,0001,0100, ..., the order of 1110), the output signal frequency is f_02, and f_02 f_01 than doubled, i.e. f_02 = 2f_01 rest on. This allows direct digital frequency synthesizer output frequency regulation.)

  • gabormask
    Gabor-function convolution masks are increasingly used in image processing and computer vision. This function simply computes the cosine and sine masks for a given width, period and orientation. The masks returned are properly normalised. It is not highly optimised - e.g. the symmetries are not used to reduce the computation. It is recommended that convolutions with these masks are done using CONVOLVE2 (available from Matlab File Exchange) to take advantage of their low rank.

    这个程序是王永良的空间普估计理论与算法中的幅相误差校正中自校正算法,找了好久找不到源程序,此程序是本人亲自编写,此方法的缺点是容易陷入局部最优解,具体看程序仿真图(This program is estimated Pu Wang Yongliang space theory and algorithms of amplitude and phase error correction in self-calibration algorithm, for a long time could not find the source, this program is a personally written, the disadvantage of this method is easy to fall into local optimal solution, specifically to see the program simulation map)
