Theoretical Study in CWNs

In this chapter, the latest information theory based theoretical results in CWNs are introduced in detail. Compared to existing works on physical layer spectrum sensing and signal processing techniques, the cognitive information concept has been proposed to characterize the information sequence from radio environment awareness results. And the uncertainty of radio environment is depicted by novel definitions of geographic entropy and temporal entropy. Furthermore, the effectiveness of cognitive techniques which can eliminate the uncertainty of radio environment are verified by the proposed cognitive information metrics.
