Performance Analysis of Underlay Cognitive Radio Systems: Estimation-Throughput Tradeoff
In this letter, we study the performance of cognitive Underlay Systems (USs) that employ power control mechanism at the Secondary Transmitter (ST). Existing baseline models considered for the performance analysis either assume the knowledge of involved channels at the ST or retrieve this information by means of a feedback channel, however, such situations hardly exist in practice. Motivated by ...
متن کاملCost-Efficient Throughput Maximization in Multi-Carrier Cognitive Radio Systems
Cognitive radio (CR) systems allow opportunistic, secondary users (SUs) to access portions of the spectrum that are unused by the network’s licensed primary users (PUs), provided that the induced interference does not compromise the PU’ performance guarantees. To account for interference constraints of this type, we consider a flexible spectrum access pricing scheme that charges SUs based on th...
متن کاملInformation Theoretic Analysis of Cognitive Radio Systems
Cognitive radios have recently emerged as a prime candidates for exploiting the increasingly flexible licensing of wireless spectrum. Regulatory bodies have come to realize that most of the time, large portions of certain licensed frequency bands remain empty [17]. To remedy this, legislators are easing the way frequency bands are licensed and used. In particular, new regulations would allow fo...
متن کاملStable Throughput Tradeoffs in Cognitive Radio Networks
Introduction: This work introduces a highly innovative approach for the operation of cognitive radio networks that is suitable for tactical wireless environments and provides a rigorous analysis of tradeoffs in network throughput that enables improved system performance. Cognitive wireless network technology, which integrates adaptive algorithms, dynamic spectrum access, and channel sensing, ha...
متن کاملFemtocell-Throughput Analysis in OFDMA-CR Networks
In OFDMA femtocell networks, the licensed spectrum of the macro users (MUs) are available to the femto users (FUs), on the condition that they do not spark off notable interference to the MUs. We contemplate wireless data for femto user (FU) / secondary user (SU) in cognitive radio (CR) networks where the frame structure split up into sensing and data transmission slots. Moreover, we review the...
