Relay Assisted Underlay Cognitive Radio Networks with Multiple Users

Lanwei Zhang, Rajitha Senanayake, Saman Atapattu +1

In this letter, we consider an underlay cognitive radio network assisted by dual-hop decode-and-forward (DF) relaying. For a general multi-user network, we adopt a max-min fairness…
