Add to ORKGIn this thesis, we tackle the problem of concurrent communications of cognitive secondary users based on packet-oriented BIC-OFDM signalling, competing against each other for the same bandwidth to minimize their packer error rate (PER)
We consider OFDMA-based cognitive radio (CR) networks where multiple secondary users (SUs) compete f...
