Cooperative spectrum sensing has a great impact to increase the performance for detecting the Primary User (PU) signal over single node sensing. Recent developments in multiple antenna techniques adjoin a new dimension in spectrum sensing. In this paper, we have proposed a multi-antenna based signal detection for multi bands considering cooperative approach with Rayleigh fading channel. In addition...
In cognitive radio communication, energy and time consumption has a key role to ensure reliable primary user signal detection. A two stage (coarse fine) spectrum sensing has drawn well-deserved attention for wideband cognitive radio communication. In this paper, it is analyzed the required time and energy for sensing, switching and transmission for wideband channel with different practical scenario...
