需将图形文件复制到D盘根目录，或修改程序中的相关文件的路径。 计算机运行可能会出现这样的警告：Warning: Function call WAVEDEC2 invokes inexact match F:Matlab oolboxwaveletwaveletwavedec2.m. > In Wnn0802 at 18 无妨，没关系的，不影响运算结果。(Need to copy files to the D graphics root directory, or modify the program in the path of the relevant documents. Computer running such a warning might appear: Warning: Function call WAVEDEC2 invokes inexact match F: Matlab toolbox wavelet wavelet wavedec2.m> In Wnn0802 at 18 anyway, it does not matter, does not affect the result of the operation.)

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.
