channel encoding in matlab

一种系统辨识方法，基于辅助模型对输出误差系统进行未知参数辨识(AM_FG.m for the output error models)

hamming 编码，线性分组码，信道编码(hamming coding, linear block codes, channel coding)

Numerically Controlled Oscillator using Embedded MATLAB

dsp源代码 matlab c 代码 代码 代码(dsp c Matlab source cod e cod e cod e)

说明：  PID控制器的优化问题就是确定一组合适的参数Ki,,Kd,Ka，使得指标达到最优。常用的误差性能指标包括ISE、IAE、ITAE、ISTE等。(The optimization problem of PID controller is to determine a set of suitable parameters Ki, KD, Ka, so as to achieve the optimal index. The commonly used error performance indexes include ise, IAE, ITAE, ISTE, etc.)

语音信号分析与处理及其MATLAB实现,语音信号处理(Speech Signal Analysis and Processing and MATLAB realize, voice signal processing)

实现维纳滤波用于语音增强。第一步采用频域谱函数计算最佳的维纳滤波器，再对输入带噪信号进行滤波；第二步是在此基础上的改进，用了自适应的思想，及时根据当前帧的状态更新修正滤波器的系统函数，得到更精确的无噪语音信号。第三步是采用自适应LMS方法，在时域迭代计算滤波器系数，迭代次数足够多时可得到较准确的有用信号。(Implement wiener filtering used in speech enhancement. First step optimum wiener filter is obtained by using the frequency spectrum function, again to input the signal with noise filtering The second step is the improvement on the basis of this, with the idea of adaptive, and in a timely manner according to the current frame updates correction system function of the filter, get a more accurate without noise speech signal. The third step is to use the adaptive LMS method, iterative calculation in time domain filter coefficient, the number of iterations enough to get the useful signal accurately.)
