The concept of cognitive radio (CR) focuses on devices that can sense their environment, adapt configuration parameters, and learn from past behaviors.
Architectures tend towards simplified decision-making algorithms inspired by human cognition.
Initial works defined cognitive engines (CEs) founded on heuristics, such as genetic algorithms (GAs), and case-based reasoning (CBR) experiential learning algorithms.
This hybrid architecture enables both long-term learning, faster decisions based on past experience, and capability to still adapt to new environments.
This paper details an autonomous implementation of a hybrid CBR-GA CE architecture on a universal serial radio peripheral (USRP) software-defined radio focused on link adaptation.
Details include overall process flow, case base structure/retrieval method, estimation approach within the GA, and hardware-software lessons learned.
Unique solutions to realizing the concept include mechanisms for combining vector distance and past fitness into an aggregate quantification of similarity.
Over-the-air performance under several interference conditions is measured using signal-to-noise ratio, packet error rate, spectral efficiency, and throughput as observable metrics.
Results indicate that the CE is successfully able to autonomously change transmit power, modulation/coding, and packet size to maintain the link while a non-cognitive approach loses connectivity.
Solutions to existing shortcomings are proposed for improving case-base searching and performance estimation methods.
