A Low-Interference Relay Selection for Decode-and-Forward Cooperative Network in Underlay Cognitive Radio
Chih‐Wen Chang, Po-Hsun Lin, Szu‐Lin Su · 2011
In the underlay decode-and-forward (DaF) cooperative cognitive radio (CR) network, an optimal relay can be selected by the conventional max-min selection on the condition of not violating the interference temperature (IT) limit. However, the max-min selection may cause some extra amount of inter
