Advanced half-duplex cooperative scheme for immersive signage transmission
Pages 316 - 319
Abstract
In Signage network systems, cooperative communication system is effective when a direct link between two nodes doesn't exist or a condition of the link is poor by allocating another node between the two nodes to relay signals. As a relay node, a half-duplex relay is widely used for ease of implementation. The half-duplex cooperative communication system using one half-duplex relay node has problems for loss of spectral efficiency and capacity. To solve these problems, a two-path relay cooperative communication system using two half-duplex relays has been actively studied. Although the two-path relay cooperative communication system solves the loss problems by transmitting signals to relay nodes alternately, the simultaneous transmission of the source node and one of the relay nodes causes inter-relay interference (IRI) at the other relay nodes. This paper proposes new two-path relay cooperative transmission method which cancels the IRI at the relay nodes and obtains the spatial diversity gain by using two antennas at the relay nodes. Unlike the conventional scheme which cancels the IRI at the destination node, the interferences aren't accumulated and aren't propagated to the destination node when the distance between the relay nodes decreases in the proposed method. Therefore, the proposed method can improve the reliability of multi-hop based signage network by canceling interference at the relay nodes.
