This paper deals with the performance study of an asynchronous multicarrier based Cognitive Radio (CR) networks.

We investigate the effect of asynchronism on the system's performance through a theoretical analysis and by using different...

In this paper an empirical study on quantitative parameters involved in spectrum mobility prediction are discussed in detail.

These parameters are studied extensively because they play a vital role in the spectrum handoff process moreover the impact of these parameters in various handoff methods can be used to predict the effectiveness of the system.

more The innovation of wireless technologies requires dynamic allocation of spectrum band in an efficient manner.

This has been achieved by Cognitive Radio (CR) networks which allow unlicensed users to make use of free licensed spectrum, when the licensed users are kept away from that spectrum.The evaluation mechanism represents Receiver Operation Characteristic (ROC) of each approach, as w design of each approach.Finally, a proposed modification has been done on DTED method to enhance its performa MDTED.The cognitive radio makes decision, switching from primary user to secondary user and vice-versa, based on its built-in interference engine.It allows secondary users to makes use of a channel based on its availability i.e.In this paper a review and evaluation of different Energy Detection (ED) based spectrum sensin presented.Conventional Energy Detector (CED) and Double Threshold Energy Detector (DTED) have been i evaluation.For a sensing time interval ranging from 0.05 ms to 5ms, the experimental results show that the polynomial classifier has a better performance compared to the conventional energy detector in terms of the misclassification rate, especially at lower SNR values.Cognitive Radio (CR) is a modern trend of wireless communication with goal to achieve higher frequen overcome the problem of spectrum vacancy.In this paper, a cognitive radio system is implemented using National Instruments (NI) Universal Software Radio Peripheral (USRP) devices.The implemented system provides a working prototype based on real data generated and collected by...
