该算法是通过统计图像某一边缘法向方向的灰度变化情况来进行评价。即灰度变化越剧烈， 边缘越清晰， 图像也越清晰。(The algorithm is an edge of the image through the statistical method to change the direction of the gray scale to be evaluated. The more intense the gray change, the more clear the edge of the image are more clear.)

基于Matlab simulink的蓄电池双向DCDC控制模型(Battery bidirectional DCDC control model based on Matlab simulink)

simulink models of pv array design

An ad-hoc network with a sender, a destination and a third station act- ing as a relay is analysed. The channels are modelled containing thermal noise, Rayleigh fading and path loss. Di® erent combining methods and di- versity protocols are compared. The amplify and forward protocol shows a better performance than the decode and forward protocol, unless an error correcting code is simulated. To combine the incoming signals the chan- nel quality should be estimated as well as possible. Information about the average quality shows nice bene¯ ts, and a rough approximation about the variation of the channel quality increases the performance even more. What- ever combination of diversity protocol and combining method is used second level diversity is observed. The relative distances between the relay and the stations has a large e® ect on the performance.
