Abstract
Recently, many studies have been performed on the relay
communication networks in order to effectively improve the
performance of communication systems in wireless fading
channels. However, previous researches have not relatively
focused on the case when there is only an indirect path to the
destination (i.e. source-relay-destination path) without the direct
route between the source and the destination. In this paper, we
evaluate and compare the performance of a dual-hop relay
communication system in accordance with the relay selection
when there is only indirect path to the destination. We also
analyze the strengths and weaknesses of each relay selection
strategies. Our simulation results show that the partial channel
information, the entire channel information, and the effect of the
presence and exchange information between the relays via the
backhaul make an effect on the relay selection. In addition, the
system performance has a significant difference according to
these channel information and system complexity.
