Spectrum Sensing Cognitive Radio Thesis

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.

In my case, somehow "luckily", I had a fixed deadline to finish the writing. Hence, these days I've been updating my webpage to include my (imperfect) thesis.

However, I still have the feeling that something is left. The title of the dissertation "Interference and Network Management in Cognitive Communication Systems" [V11] was chosen at some early stage of the work, however, it covers the two-parts of the developed work: "On the one hand, using game theoretical tools, we analyze a framework for interference management in which certain interaction is allowed between primary and secondary systems.

more 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 types of fading channel in simulations.

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".

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 ROHT algorithm is well known to compute and correct...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.more 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 an experimental laboratory setup to compare the performance of spectrum sensing algorithms based on energy detection and polynomial classifier channel sensing techniques.The simulation results showed that MDETD method has improved performance compared to DTED m values less than-3 d B.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...In order to achieve better spectrum mobility, it is mandatory to choose an effective spectrum handoff strategy with the capability of predicting spectrum mobility.The handoff strategy with its parameters and its impact is an important concept in spectrum mobility but fairly explored.
