Improving Performance of Far Users in Cognitive Radio: Exploiting NOMA and Wireless Power Transfer
In this paper, we examine non-orthogonal multiple access (NOMA) and relay selection strategy to benefit extra advantage from traditional cognitive radio (CR) relaying systems. The most important requirement to prolong lifetime of such network is employing energy harvesting in the relay to address ne...
