We present in this paper a new Blind Standard Recognition Sensor (BSRS). It is one of the most important sensor of our new concept called the "Sensorial Cognitive Radio Bubble". This concept aims at giving more sensorial information to the cognitive terminal for safety utilization. The BSRS is composed of the combination of several signal processing(More)
Cognitive radio has been claimed to be a hopeful solution to the existing conflicts between spectrum demand growth and spectrum underutilization. The basic underlying idea of cognitive radio is to allow unlicensed users to access in an opportunistic and non-interfering manner some licensed bands temporarily unoccupied by licensed users. The cognitive radio(More)
We propose to define a volume around cognitive radio equipments, typically terminals, called the ”Sensorial Radio Bubble” or SRB, the diameter of which is at the scale of the sensing possibility of the equipment. The SRB gives communication equipments the ability to explore the radio environment in order to provide knowledge about the spatial and spectral(More)
In this paper a blind standard bandwidth shape sensor is implemented on a USRP (Universal Software Radio Peripheral) platform using SDR4all tools. This sensor is a fundamental part of the so-called Blind Standard Recognition Sensor. The blind standard bandwidth sensor is based on a Radial Basis Function Neuronal Network designed in Matlab. The SDR4all(More)
Cognitive Radio (CR) has been paid much attention in both academic and industrial domains during the last years for its potential capability to solve to the so-called spectrum scarcity problem. The CR concept arose as a result of the current spectrum underutilization, which was demonstrated in a number of spectrum measurement campaigns. The main objective(More)
