Automatic real-time spectrum sensing using energy detection in software defined radio

Includes bibliographical references (page 52)The purpose of this graduate project is to design a real-time spectrum sensing system using software defined radio. The uniqueness of software defined radio is the concept of replacing many of the hardware components in a traditional radio communication system with software algorithms and coding. The scope of this project will be on spectrum sensing ??? to be able to automatically detect active signals in the desired frequency spectrum.\ud \ud The hardware components used in this graduate project are the Universal Software Radio Peripheral and the Agilent function generator. The graphical user interface and algorithm programming are performed in MATLAB. The spectrum sensing system will scan a portion of the frequency spectrum, determine the presence of signals, and display the three highest signal peaks in a given band. This paper will elucidate spectrum sensing's strengths and weaknesses as well as possible future work
