通过蒙特卡罗仿真说明直接序列扩频系统在抑制正弦干扰的有效性(Monte Carlo simulation shows direct sequence spread spectrum system in the sinusoidal interference inhibited the effectiveness)

等间距线性阵列，阵元数M=8，阵元间距d= λ /2， 等幅加权，无噪声。 分别仿真计算目标方位φr =0°、30°时的阵列方向图。 (The spacing of the linear array, and the array element number M = 8, the array element spacing d = λ/2, equal amplitude weighted, no noise. Respectively simulation calculation the target azimuth φr = 0,30 array pattern.)

包括调制，解调，信噪比计算，抑制载波型差分相位调制，实现典型相关分析，music高阶谱分析算法，随机调制信号下的模拟ppm，是小学期课程设计的题目，采用了小波去噪的思想，针对EMD方法的不足。( Includes the modulation, demodulation, signal to noise ratio calculation, Suppressed carrier type differential phase modulation, Achieve canonical correlation analysis, music higher order spectral analysis algorithm, Random ppm modulated analog signal under Is the topic of the elementary school stage curriculum design, Using wavelet denoising thought, For lack of EMD.)

说明：  这是基于matlab编程实现的潮流计算，包括PQ计算、雅克比计算(This is power flow calculation based Matlab, including PQ calculation.)
