ISM spectrum is becoming increasingly populated with various wireless technologies, rendering it a scarce resource. Consequently, wireless coexistence is increasingly vulnerable to new wireless devices attempting to access the same spectrum. This paper presents a novel method for identifying wireless technologies through the use of simple energy detection techniques. Energy detection is used to measure...
Spectrum assigned by the Federal Communication Commission (FCC) for public safety has not been fully utilized. As such, communication service providers and equipment vendors desire to examine the feasibility of recouping their investment in spectrum purchase and management. We propose a cost-effective solution by introducing a cognitive extension that achieves desired frequency agility while utilizing...
Recent technological advances in cognitive radio based on software defined radio platforms have extended the capabilities of wireless communication systems. The unique ability to alter communication protocols to meet changing system demands makes cognitive radio suitable for wireless applications otherwise difficult to implement using conventional wireless terminals. One such wireless application...
