For feature reduction, feature fusion, correlation analysis, Using matlab written narrowband noise occurs, Linear array using cut than learning laid upon the right control of the main sidelobe ratio.

Phased array antenna pattern (Chebyshev weights), matlab implements five gray correlation degree computing model, Modern signal processing used in the spectral estimation in matlab.

刻画随机过程X(t)在各个独立时刻的概率统计特性,反映不了随机过程的内在相关性(Characterize the probability statistical properties of stochastic process X (t) at each independent moment, which can not reflect the inherent correlation of stochastic process)

MATLAB代码生成Gold码、m序列并得到自相关、互相关函数。之后进行BPSK调制，验证扩频通信的错码率的降低。(Gold code and m sequence are generated and autocorrelation and cross-correlation functions are obtained. Then BPSK modulation is carried out to verify the reduction of error rate of spread spe
