设计一维纳滤波器。 （1）产生三组观测数据，首先根据s(n)=as(n-1)+w(n)产生信号s(n)，将其加噪(信噪比分别为20dB，10dB，6dB)，得到观测数据x1(n)，x2(n)，x3(n)。 （2）估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L，N对实验结果的影响。 (Design a Wiener filter. (1) generate three sets of observations data, first according to s (n) = as (n-1)+w (n) to generate a signal s (n), which add noise (SNR respectively 20dB, 10dB, 6dB), obtained observation data x1 (n), x2 (n), x3 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss changes affect L, N of the experimental results.)

G729编码和解码的Matlab源程序 调用方法： 1.需要编码时，在 Matlab命令行下输入"G729code(speech)"(请务必保证 speech是已经存在在 Matlab工作区的一个行向量，其中是语音数据)，然后你会在你的文件夹下看到一个"coding.bit"的文件。 2.需要解码时，把"coding.bit"的文件复制到"G729 decoder"的目录下，在Matlab命令行下输入"G729decodermain"，然后你会在文件夹下看到"syn_speech.wav"，那就是重构语音。 enjoy it! (G729 encoding and decoding of the Matlab source code to call methods: 1. The need for coding at the Matlab command line, enter )

介绍了用MATLAB来实现曲线拟合的方法，对进行该方面学习的人很有效(Described curve fitting using MATLAB to implement the method aspects of the conduct of the study were very effective)
