BOC调制，原始信号扩频之后与方波相乘，使得频谱分裂，抗干扰能力很强！(BOC modulation, spread spectrum, after the original signal multiplied with the square wave, making the spectrum division, a strong anti-interference ability!)

this is a matlab code of audio compression

本手册介绍matlab中各种函数的应用，对matlab使用者帮助很大(This manual describes the application of various functions in matlab, matlab users of great help)

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.)
