Efficient Single Relay Selection Scheme For Cooperative Communication

Abstract

This paper proposes a single relay selection scheme in
cooperative communication. Decode-and-forward scheme is
considered when a source node wants to cooperate with a single relay
for data transmission. To use the proposed single relay selection
scheme, the source node makes a little different pattern signal which is
not complex pattern and broadcasts it. The proposed scheme does not
require the channel state information between the source node and
candidates of the relay during the relay selection. Therefore, it is able
to be used in many fields.
