Performance analysis of best relay selection scheme for amplify-and-forward cooperative networks in identical Nakagami-m channels
( IEEE , 2010 , Conference Paper)In cooperative communication networks, the use of multiple relays between the source and the destination was proposed to increase the diversity gain. Since the source and all the relays must transmit on orthogonal channels, ... -
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
( IEEE , 2010 , Conference Paper)Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ... -
