代码说明:

  it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed

    邻域平均法滤波 原图像画面清晰,添加勒椒盐噪声后图像上产生勒明显的黑色斑点(噪声),用不同模板的平滑滤波处理后图像上的噪声消失,但是图像变得模糊,并且,使用的模板越大,对图像的去噪效果越好,同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)

    这是一个综合性的仿真程序。包括:用matlab生成一个FIR滤波器,得到滤波器系数及阶数;再用C语言产生一个混合频率的数字信号,之后将生成的数据样点送入到DSP主程序进行数字滤波,DSP主程序算法用的是循环缓冲区算法,这一部分在CCS上实现。(This is a comprehensive simulation program. Comprising: generating a matlab FIR filter, to obtain the filter coefficients and order then mixed to produce a C-frequency digital signal, and then the resulting data samples into the main program to the DSP for digital filtering, DSP main algorithm using a circular buffer algorithm, this part of the CCS to achieve.)

    关于用遗传算法改进BP神经网络的matlab实现(转引) ga优化神经网权值&阈值程序。 优化的基本原理和过程很多论文可以查到,在此不必赘述我就把用gaot5的小程序贴在下面吧,也是y=1/x(为看的方便,比较繁杂的也有) (About matlab improved BP neural network using genetic algorithm implementation (quoted) ga optimizing neural network weights & Threshold Program. Optimization of the basic principles and procedures can be found in many papers, this does not have to go into details, I' ll stick with gaot5 small program below it, is y = 1/x (for watching convenience, there are also more complicated))
