Spectrum sensing is the fundamental task for Cognitive Radio (CR). To overcome the challenge of high sampling rate in traditional spectral estimation methods, Compressed Sensing (CS) theory is developed. A sparsity and compression ratio joint adjustm

Efficient and reliable subcarrier power joint allocation is served as a promising problem in cognitive OFDM-based Cognitive Radio Networks (CRN). This paper focuses on optimal subcarrier allocation for OFDM-based CRN. We mainly propose subcarrier all

Spectrum sensing is the fundamental task in Cognitive Radio (CR). Due to the fact that signal sparsity level is usually unavailable at CR receiver, this paper presents a blind compressive spectrum sensing approach when the sparsity level is unknown.
