Cognitive Radio Technologies: Services and Software for Intelligent Wireless Networks
CRT has extensive experience in the design and implementation of the cognitive radio (CR) systems. CRT's CR system solution incorporates a general cognitive engine software system which has been used to control all aspects of a radio’s waveform and the link quality of service (QoS). The cognitive engine combines the artificial intelligence and wireless communications to provide cognitive service and performance optimization from physical to network layer.
The cognitive capabilities are enabled by the classical machine learning techniques such as artificial neural networks, evolutionary algorithms and cased based knowledge system.
Advanced signal processing algorithms have been designed and implemented to enable the awareness of the wireless environment and performance optimization across multiple communication layers.
Through a developed hardware independent radio interface the cognitive engine has been ported to a variety of platforms such as GNU Radio and IRIS radio.
CRT's CR solution provides
wireless environment awareness from spectrum energy detection to specific waveform format decoding
application specific cognitive radio functionalities
radio resource management optimization
cross-platform algorithm porting and fast field deployment
