Software-Defined Radio - Basics and Evolution to Cognitive Radio
We provide a brief overview over the development of software-defined or reconfigurable radio systems. The need for softwaredefined radios is underlined and the most important notions used for such reconfigurable transceivers are thoroughly defined. The role of standards in radio development is emphasized and the usage of transmission mode parameters in the construction of software-defined radio...
متن کاملCognitive Radio Communications and Software Defined Radio
Increasing demands for high speed wireless access gave rise to new approach to radio communications and spectrum management – Cognitive Radio (CR). One of the key components of cognitive radio – dynamic spectrum access – shows a way to overcome the scarcity of one of the natural resources – radio frequency spectrum. The research in the domain of CR spans the wide area from information and signa...
متن کاملCognitive 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...
متن کاملSoftware Defined Adaptive Codec for Cognitive Radio
Recently, Cognitive Radio has been proposed as a promising technology to improve spectrum utilization. A highly flexible SDR (Software defined Radio) system needs to configure each of its blocks to give optimum performance over the available bandwidth. Present work discusses an approach for software defined adaptive coder yielding minimum BER (Bit error rate) for emergency services over cogniti...
متن کاملA Software-defined Radio Prototyping Platform for Cognitive Radio Applications
During the last decades, the demand for higher data rates in wireless communication systems grew steadily. While the number of communication systems increased significantly, the amount of available spectral resources has remained constant. To exploit spectral resources more efficiently, cognitive radio concepts have become of utmost interest. The goal of cognitive radio systems is to sense the ...
