Software Defined Radio Rf Receiver

The objective of this project is to design A Computer Software Defined VHF Radio Receiver in the range of frequencies (85 MHz to 150 MHz) with minimum hardware and high flexibility for the University of Khartoum educational ground station, also the product aimed to be available for upgrading and modification by the students, graduates and researchers.Recently the concept of the Software Defined Radio (SDR) appeared and offered massive reduction on the hardware design architecture of the conventional radio receivers and turning it into a software segments. Giving high flexibility, compatibly, performance and configurability. It can be also easily upgraded with new features and services. Leading to further developments on its basic functions without changing the hardware core. The purpose of this project is to design A Computer Software Defined VHF Radio Receiver for the University of Khartoum Educational Ground Station in the range of frequencies of (85 MHz to 150 MHz). The signal will be received by the receiver and then the demodulation processes will be applied on it by a computer software as well as other functions such as filtering and amplification instead of hardware circuit stages specialized to do these functionalities. The scope of this project will focus on the hardware design and implementation of the receiver. The final testing of the system will be conducted using an open software program installed on the computer. The project is software designed, computer simulated and hardware implemented as Printed Circuit Board (PCB). The results of the designed system were satisfactory and close enough to the expected theoretical assumption and objectives of the project. Leading to a promising future advancements and developments
