Adaptive--filter--denoising

匹配滤波相关器的Matlab实现的源代码(Matched filter correlator realization of the source code for Matlab)

digital to analog converter

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.
