Detection Of Ofdm Signals Using Pilot Tones And Applications To Spectrum Sensing For Cognitive Radio Systems, Ahmed Temtam

Electrical & Computer Engineering Theses & Dissertations

Nowadays there are an increasing number of wireless devices which support wireless networking and the need for higher data rate communication is increasing rabidly. As more and more systems go wireless, approaching technologies will face spectral crowding and existence of wireless devices will be an important issue. Because of the limited bandwidth availability, accepting the request for higher capacity and data rates is a challenging task, demanding advanced technologies that can offers new methods of using the available radio spectrum. Cognitive radio introduces a key solution to the spectral increasing issue by presenting the opportunistic usage of spectrum that is …
