Book Description
Then the expressions are derived for the false alarm probability and miss detection probability. Finally, we investigate the associated penalty function for both false alarm and miss detection, from which we attempt to find the optimal threshold to minimize the total penalty due to wrong decisions. Extensive simulations are performed, which are consistent with theoretical analysis. It is concluded that secondary users mobility has a significant impact on miss detection probability, but not on false alarm probability. The optimal threshold can be also found from numerical results to achieve the minimum total penalty.

Book Description
The rapid usage of wireless-communications in personal, commercial and governmental capacities, efficient spectrum utilization has become a prime topic of interest. Most of the licensed bands suffer from under-utilization and less spectral occupancy of spectrum. Cognitive radio technology promising solution to the problem of low spectral occupancy and inefficient utilization of the licensed radio spectrum. A prime constituent of the cognitive radio technology is spectrum sensing. Energy detection (ED) is one of the popular spectrum sensing technique for cognitive radio. In this work, I Proposed RTL 2832U SDR stick is suitable for energy detection based spectrum sensing method. In this experiment, we capture the real time signal coming from the BTS over the different city in rural & urban area using an RTL 2832U SDR stick to decide the frequency band available or not. The GNU Radio software allows for the implementation of Energy detection spectrum sensing technique using the RTL-SDR.

Book Description
A cognitive radio (CR) system offers a more efficient spectrum utilization as compared to conventional wireless transmission systems. In particular, in a so-called interweave CR scenario, spectrum sensing is a crucial component responsible for acquiring information about the existence and strength of a primary user (PU) signal, since the subsequent spectral access depends on that information. A wide range of spectrum sensing techniques has been proposed to suit various requirements and system scenarios. These techniques differ in many respects like e. g. the computational complexity, the required observation frame length as well as the resulting sensing performance. Spectrum sensing in different scenarios and under various models is investigated in this thesis. Here, both temporal and spatial correlations of the received signals are considered for designing space-time sensing algorithms.
