Projects:2020s1-1110 Cognitive Radio System

Abstract

The objective of this project was to research and develop a Cognitive Radio System. Cognitive Radio is a wireless system that adapts to its environment utilize the already congested frequency spectrum to provide stable and efficient communications for data transfer as well as prolonging battery life due to less power being used for transmission. Two main parts will make up this system, that being a reconfigurable antenna and a cognitive transmitter. The antenna will be designed to be frequency reconfigurable and will utilize discrete switching mechanisms such as digitally tunable capacitors to change its frequency depending on the requirements of the transmitter system. It will also provide a control interface for the transmitter subsystem. An SDR will be the platform used for the design of the radio transmitter. A control system will be implemented to detect and change the characteristics of the system based on the dynamic properties being continuously tracked by the antenna, and will also drive the control interface of the antenna subsystem.
