代码说明:

  DCT变换1、 提取彩色图像,将图像大小限制为512*512*3; 2、 提取彩色图像三个颜色分量的矩阵,每个矩阵单独处理; 3、 将矩阵分为8*8的块,做DCT变换; 4、 提取每个块的一部分DCT系数做IDCT变换,显示基本图像; 5、 再提取每个块的一部分DCT系数做DCT反变换,得到增强层1,与前一次得到的数据叠加,得到质量更好的图像。 (DCT transform)

    1. BPSK modulation of data which ever you input (default data is “MANIPAL REDDY”). 2. MANIPAL REDDY is changed into ASCII Format and into two-bit format for BPSK Modulation. 3. Chaos is used for spreading the binary bit sequence. 4. Uniformly distributed Noise is added to Spread signal. 5. After reception Chaotic Chip sequence is used to recover message . 6. Filter is used for removing spikes and noise. 7. Note the filter is used is just for showing a little realisitic picture. 8. Appropriate filter should be used. 9. The original data in binary and recovered data in binary format are compared

  • 用“时域最小平方误差准则” 设计IIR DF
    试用时域最小平方误差准则(最小平方逆设计)设计一个具有四项系数的IIR DF的系统函数,使其在y(n)=[3,2,1]输入激励下,输出v(n)逼近d(n)=[2,0.2,0.05]。令v(-1)=v(-2)=0。求出v(n)的前8个样值与d(n)进行比较。用matlab实现了此要求。(trial at the least square error domain guidelines (minimum inverse square design) design with a four DF IIR coefficient of the system function, so in y (n) = [3,2,1] incentive to import, export v (n) approximation d (n) = [2,0.2,0.05]. So v (1) = v (2) = 0. Get v (n) of eight samples value d (n) comparisons. Using Matlab realization of this request.)
