SIMULINK仿真实现BPSK在莱斯衰落+AWGN信道中的调制与解调，并分析了误码率和星座图等等参数。(SIMULINK simulation of BPSK in Rician Fading realize+ AWGN channel modulation and demodulation, and analyzes the bit error rate and constellation parameters and so on.)

Gradient information serves several purposes. It can relate the structure of objects in an image, identify features of interest for recognition/classification directly or provide the basis of further processing for various computer vision tasks. For example, "edges," noted by regions of high gradient magnitude, are central to the task of identifying defects in circuitry. A sample "edge-detected" image using the Image Processing Toolbox for MATLAB is shown where locations marked by white are those points that are indicative of high gradient magnitude, which can also be described as regions of high pixel contrast.
