Distributed spectrum sensing via energy detection in cognitive radios

Altay, Can. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)

Energy Detection is widely studied spectrum sensing system to detect signal energy due to its simplicity and lack of requirement signal characteristics. This thesis focuses on two main problems on distributed detection of ...
Location based spectrum sensing in cognitive radio systems

Alimoğlu, Fernaz. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)

Cognitive radio is a promising solution to the spectrum utilization problem in time and space. One of the most critical points of cognitive radio is spectrum sensing. A reliable sensing is important for not disturbing the ...
User selection and density based decision method for cooperative spectrum sensing in cognitive radio networks

Çimentepe, Gonca Eryiğit. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)

Radio spectrum is one of the scarce source and its importance is increasing in recent years due to rapidly developing new technologies. Today's wireless networks use fixed spectrum assignment policy which causes inefficient ...
