Description: 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. Platform: |

level diversity is observed. The relative distances between the relay and the
stations has a large e® ect on the performance. Platform: |
