说明：  实现random forest,一种较新的，有效地分类算法(random forest classification)

说明：  为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环 谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频 率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信 噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2 tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2 able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the decision threshold correspond to different false alarm probability , as a result , making the sensing users can detect licenced users signal under lower signal in noise ratio (SNR) .)

matlab编程初级教程，是初学者的学习宝典，简单易懂(The primary matlab programming tutorial is for beginners to learn canon easy to understand)

设有一个随机信号 服从AR(4)过程，它是一宽带过程，参数如下： 我们通过观测方程 来测量该信号， 是方差为1的高斯白噪声，用LMS算法和RLS算法通过观测方程来估计原信号。并用Matlab对此问题进行仿真。 (There is a random signal obedience AR (4) process, which is a broadband process parameters are as follows: We are measured by observing the signal equation is a Gaussian white noise variance, with the LMS algorithm and RLS algorithm to estimate the observation equation the original signal. This issue with Matlab simulation.)
