用于信号特征提取、信号消噪，ICA（主分量分析）算法和程序，随机调制信号下的模拟ppm，粒子图像分割及匹配均为自行编制的子例程，matlab编写的元胞自动机，仿真图是速度、距离、幅度三维图像，采用波束成形技术的BER计算。- For feature extraction, signal de-noising, ICA (Principal Component Analysis) algorithm and procedures, Random ppm modulated analog signal under Particle image segmentation and matching subroutines themselves are prepared, matlab prepared cellular automata, FIG simulation speed, distance, amplitude three-dimensional image, By applying the beam forming technology of BE.
