利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

matlab的常用命令速查，收录了matlab的多种常用命令，很好使用(commonly used commands Info matlab, matlab includes a variety of commonly used commands, a very good use)

Recursive stochastic forecaster k steps ahead of AR(1) time series given initial value & computation of stepwise dynamic multiplier

这是一个有预测功能的程序，还没有进行优化，可供大家作为基础来加以改进，但是大概的预测方向都是准确的(This is a prediction function of the procedure have not yet optimized for the U.S. used as the basis to be improved, but perhaps the direction of the prediction is accurate)

直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )
