cognitive radio IEEE PAPER, IEEE PROJECT
Cognitive Radio (CR) is an adaptive, intelligent radio and network technology that can automatically detect available channels in a wireless spectrum and change transmission parameters enabling more communications to run concurrently and also improve radio operating behavior.
The impact of information technologies is creating a new world yet not fully understood. The extent and speed of economic, life style and social changes already perceived in everyday life is hard to estimate without understanding the technological driving forces behind it. Thi sEnabling cognitive radio (CR) requires revisiting the traditional task of spectrum sensing with specific and demanding requirements in terms of detection performance, real-time processing, and robustness to noise. Unfortunately, conventional spectrum sensing methods

Abstract Cognitive Radios (CRs) use dynamic threshold estimation (DTE) techniques to better detect primary user signals under noise uncertainty regimes. However, DTE techniques have rarely been compared before, particularly under the one tier CR networkA cognitive radio (CR) system aims at an efficient utilization of the spectrum below 6 GHz suitable for mobile communications by enabling a secondary access to the licensed spectrum while ensuring a sufficient protection to the licensed users. Despite the fact that an

Multi-hop routing protocol in cognitive radio mobile ad hoc networks (CRMANETs) is a critical issue. Furthermore, the routing metric used in multi-hop CRMANETs should re-flect the bands availability, the links quality, the PU activities and quality of service (QoS)Cognitive radio (CR) technology is a promising solution to the inevitable problem of spectrum scarcity and underutilization. Cognitive radios can perform spectrum sensing, dynamically identify unused spectrum, and opportunistically utilize those spectrum holes for
