中文说明：表示出两帧图像间各个像素点的相对情况，是国外的成品模型，详细画出了时域和频域的相关图，匹配追踪和正交匹配追踪，各种kalman滤波器的设计，单径或多径瑞利衰落信道仿真，采用波束成形技术的BER计算。
English Description：
It represents the relative situation of each pixel between two images, which is a foreign finished model. It draws the correlation diagram in time domain and frequency domain, matching pursuit and orthogonal matching pursuit, the design of various Kalman filters, single path or multi-path Rayleigh fading channel simulation, and BER calculation using beamforming technology.
