说明： 4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

vigenere
vigenere密码在起初的破译中是靠穷举法，找出与阅读习惯最适合的明文，但是也可以先缩小穷举范围，再查找(vigenere initial crack passwords by brute-force method is to identify the most suitable and clear reading habits, but can also be reduced exhaustive range, and then find)

AR模型的Yule-Walker方程.1927年，Yule提出用线性回归方程来模拟一个时间序列。Yule的工作实际上成了现代谱估计中最重要的方法——参数模型法谱估计的基础。Walker利用Yule的分析方法研究了衰减正弦时间序列，得出Yule-Walker方程，可以说，Yule和Walker都是开拓自回归模型的先锋。(The Higher-Order Yule-Walker method.)

Synchronize
说明： 由于使用了大量数目的子载波，这就使得多载波系统对多种同步误差都很敏
感。同步误差可分为两大类:载波相位
(due to the use of the large number of subcarriers, which makes multi-carrier systems for a variety of synchronization errors are very sensitive. Synchronization error can be divided into two categories : carrier phase)

利用小波变换多尺度分析的特性,在小波域的各个尺度上选取不同的阈值对基本的频域谱减法进行改进,并且根据清浊音各自不同的特点,在去噪过程中加以分离,保留了语音中的清音成分,使语音更加饱满。(The use of multi-scale wavelet analysis of the characteristics of the individual in the wavelet domain scale threshold select a different frequency domain of the basic spectral subtraction to improve and, in accordance with their respective Qingzhuo sound different characteristics, in the denoising process be separated from the retained voice of the voiceless in the composition, more full of voice.)
