We consider the problem of selecting the packet size, the Forward Error Correction (FEC) coding rate, and the duration of the spectrum sensing interval, which maximize the communication goodput (payload bits correctly received per unit time) of the S

We consider a cognitive radio scenario where the communication between two secondary users (SUs) exploits opportunistic spectrum access (OSA) over a wireless channel licensed to primary users (PUs). Assuming a slotted MAC over a single frequency chan

This paper considers the problem of scheduling realtime traffic in OFDMA systems. We present two heuristics with the objective of meeting as much deadlines as possible, or equivalently, minimizing the number of missed deadlines. The proposed heuristi

In this paper, we investigate a scheduling problem in systems adopting OFDMA transmission technique at the physical layer, like WiMAX (IEEE 802.16) systems. In such systems, carriers with different rates must be assigned to users, each carrier being
