Martin’s article on the role of cognitive radio technology within the world of software-defined radio provides an excellent introduction to this subject. Cognitive radios, being aware of their environment and capable of making operating decisions based on it, have a great potential to increase the performance of wireless devices and make more efficient use of under-utilized spectrum. The following blog posts cover a range of theoretical and practical techniques for implementing cognitive radio capabilities on Nutaq SDR platforms:
