AF or DF, and How to Configure an Optimal Mixed AF-DF Relay System?
Channel fading due to multipath propagation in wireless communication systems causes a significant degradation in the received signal quality. Using various diversity reception techniques, we can mitigate signal degradation problem due to channel dispersion. However, due to the space limitations at mobile units, it is extremely difficult to have more than one antenna at the handsets. Thus, the cooperative relay technology provides us an excellent solution for high data-rate wireless transmission as required in the futuristic cellular and ad-hoc wireless communications systems.
