Optimum Spectrum Sensing Approaches in Cognitive Networks,n energy constraint. This may not be the optimum solution to sense the channel. In this chapter, we present various approaches to sense the spectrum availability dynamically using various parameters including energy which may not only improve the packet delivery ratio but also reduces the overhead.

Learning Strategies in Cognitive Radio Involving Soft Computing Techniques, knowledge base, reasoning block, and learning phase. As part of cognitive process, the radio observes, orients, takes decisions, and evaluates the outcomes of decisions taken which is part of the learning phase. There are a variety of learning techniques enabling prediction of various operating and

Hence, it is imperative to explore cognitive spectrum sharing techniques to enhance spectrum utilization efficiency through the development of hybrid satellite-terrestrial communication systems. In this regard, t
