Achievable Rates and Scaling Laws for Cognitive Radio Channels
Cognitive radios have the potential to vastly improve communication over wireless channels. We outline recent information theoretic results on the limits of primary and cognitive user communication in single and multiple cognitive user scenarios. We first examine the achievable rate and capacity regions of single user cognitive channels. Results indicate that at medium SNR (0–20 dB), the use of...
متن کاملComments on "Achievable Rates in Cognitive Radio Channels"
In a premier paper on the information-theoretic analysis of a two-user cognitive interference channel (CIC) [1], Devroye et al. presented an achievable rate region for the two-user discrete memoryless CIC. The coding scheme proposed by Devroye et al. is correct but unfortunately some rate-terms in the derived achievable rate region are incorrect (in fact incomplete) because of occurring some mi...
متن کاملAchievable Outage Rates in Cognitive Radio Networks under Imperfect Spectrum Sensing
In this paper, we aim at deriving the outage rates achieved by the primary user due to spectrum sensing in a cognitive radio network, that we call sensing-induced primary outage rates. To reach this goal, in the first step, instead of classical spectrum sensing techniques that evaluate sensing performance only based on correct detection of the presence of the primary user’s signal, we propose a...
متن کاملOn Achievable Performance of Cognitive Radio Systems
In this contribution1, we investigate the idea of using cognitive radio to reuse locally unused spectrum to increase the total system capacity. We consider a multiband/wideband system in which the primary and cognitive users wish to communicate to different receivers, subject to mutual interference and assume that each user knows only his channel and the unused spectrum through adequate sensing...
متن کاملOn the Capacity of Underlay Cognitive Radio Systems
On the Capacity of Underlay Cognitive Radio Systems Lokman Sboui Due to the scarcity of frequency spectrum in view of the evolution of wireless communication technologies, the cognitive radio (CR) concept has been introduced to efficiently exploit the available spectrum. This concept consists in introducing unlicensed/secondary users (SU’s) in existing networks to share the spectrum of licensed...
