Wideband Spectrum Sensing by Model Order Selection [PDF]
IEEE Transactions on Wireless Communications, 2015 Spectrum sensing is an essential functionality in cognitive radio (CR) systems allowing us to discover spectrum opportunities and enabling primary user (PU) protection. Wideband spectrum sensing (WS) improves the awareness of the surrounding radio environment by jointly monitoring multiple frequency bands.

Spectrum Sensing in Wideband OFDM Cognitive Radios [PDF]
IEEE Transactions on Signal Processing, 2010 In this paper, spectrum sensing of an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) is addressed. The goal is to identify the portions of the spectrum that are unused by primary user systems and other CR systems, called existing user (EU) systems altogether, with the emphasis on conquering the challenge imposed by ...
