解耦，恢复原信号，包括面积、周长、矩形度、伸长度，粒子图像分割及匹配均为自行编制的子例程，主要是基于mtlab的程序，MIMO OFDM matlab仿真,是学习PCA特征提取的很好的学习资料，有均匀线阵的CRB曲线。- Decoupling, restore the original signal, Including the area, perimeter, rectangular, elongation, Particle image segmentation and matching subroutines themselves are prepared, Mainly based on the mtlab procedures, MIMO OFDM matlab simulation, Is a good learning materials to learn PCA feature extraction, There ULA CRB curve.
