ChebyshevExpansion
给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列
另外该函数用cos(x)项傅里叶级数展开一个多项式(
ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04
Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with
highest power on the left, expand f(x) as a sum of scalar multiples of
Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k
running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)

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) .)

近20年来，阵列信号处理已成为信号处理的一个重要分支，本次实验就是通过MUSIC（Multiple Signal Classification）算法对混叠有高斯白噪声的双信源信号进行频谱分析。(Space there is more than one letter (No.) source, it is often necessary to separate these signals in order to track or detect the spatial signal we are interested in, inhibition of those who are considered interference signal. To this end, the need to use the antenna array to receive multiple spatial signal analysis and processing of the the spatial signal received by the antenna array known as array signal processing. The past 20 years, array signal processing has become an important branch of signal processing, this experiment is the MUSIC (Multiple Signal Classification) algorithm aliasing Gaussian white noise dual source signal spectrum analysis.)
