more In this paper, an optimized Recursive One-Sided Hypothesis Testing (ROHT) threshold estimation algorithm for energy detection based on Cognitive Radio (CR) application is presented.

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...

My dissertation examination took place a couple of weeks ago. Now I can say that one of the unexpected problems of doing a Ph D is to decide "what is enough".

Spectrum Sensing Cognitive Radio Thesis Differentiation Solved Problems

In some cases you can decide it based on the number of publications, but you probably have a lot of unfinished work which would be nice to include. But as the quote says, perfection is the enemy of completion.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.This performance evaluation was in term of BER using Matlab when different types of Rayleigh fading channels are used (Pedestrian A, Vehicular A,....).Simulation results showed that the pedestrian and indoor Hiperlan/2 channel give the best performance for our asynchronous OFDM based CR network.Spectrum sensing is the basic step in CR, which enables it to distinguis (idle or busy). more Cognitive Radio (CR) is a modern trend of wireless communication with goal to achieve higher frequen overcome the problem of spectrum vacancy.Spectrum sensing is the basic step in CR, which enables it to distinguis (idle or busy).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.Since asynchronous interference could be very harmful on the system's Qo S level, our work was principally to develop a new theoretical approach to model the asynchronous interference in CR networks.Furthermore, we are leading a comparison between different fading channel models which are suited to wireless CR networks.
