Building Cognitive Radio

Building Cognitive Radio System Using Matlab

Cognitive radio is an emerging and fascinating technology for the opportunistic use of under-utilized spectrum that promises to change the future technological trends forever if employed properly. This work focuses on the practical implementation of a cognitive radio network.

Building a Cognitive Radio: From Architecture Definition to Prototype Implementation

Cognitive Radio Network Application Radio

Application of cognitive radios as the wireless terminals in ad hoc networks in emergency situations has distinct advantages. Better bandwidth, interoperability, avoidance of interference, and ant-jamming capabilities are a few such advanta This paper deals with ad hoc networks incorporated with cognitive radios, which acts as wireless terminals, that can be used in emergency situations and can...

Security in Cognitive Radio Networks Security in Cognitive Radio Networks

While bringing the potential for solving the spectrum underutilization problem using methods such as dynamic and opportunistic spectrum access, Cognitive Radios (CRs) also bring a set of security issues and potential breaches that have to be addressed. These issues come out mainly from the two important capabilities implemented within CRs: their cognition ability and reconfigurability. This cha...

Cognitive Radio Applications in Software Defined Radio

The topic of cognitive radios has been garnering a great deal of attention in the past several years. Opinions regarding the level of sophistication necessary to qualify a system as cognitive vary widely, and discussions have ensued regarding this technology. The software defined radio forum is also involved and has working group activity in the area of cognitive radio. Some of the working grou...
