Chapter 2Spectrum Sensing Techniques
In order for a DSA wireless system to observe, orient, decide, and act as explained in the previous chapter, it must be aware of the spectrum sensing parameters and how they relate to the sensed frequency band characteristics. This chapter addresses the different spectrum sensing techniques that can be utilized. The spectrum sensing techniques covered in this chapter are presented in a generic way while pointing to which techniques can be implemented on specialized hardware and which techniques can be implemented as same‐channel for in‐band sensing. Notice that the focus of this chapter is not limited to spectrum sensing performed for a secondary user to use some spectrum bands opportunistically. As the previous chapter explained, there are many DSA cases in defense and commercial applications that go beyond the secondary user scope and are not necessarily in the cognitive radio domain. The focus of this chapter is also not limited to spectrum sensing techniques that can be developed for distributed cooperative MANETs. The spectrum sensing techniques explained here are generic and can be used for local decisions, distributed cooperative decisions, centralized decisions, or hybrid decisions, and for different types of communication systems.
2.1 Multidimensional Spectrum Sensing and Sharing
Spectrum sensing provides multidimensional spectrum usage characteristics over time, space, and frequency bands. Spectrum sensing can range from simple ...
