Utilizing Software Defined Radios for Increased Bandwidth in Satellite Communications

Abstract

This research explores the background and future possibilities of using cooperative satellites equipped with Software Defined Radios (SDRs) to combine their bandwidth and increase their signal reliability. Software Defined Radios are a potential solution to realize various software applications that support a reconfigurable and adaptive communication system without altering any hardware devices or features. This benefit, along with others that are offered by SDRs and the ongoing improvements in commercial digital electronics have sparked an interest in developing small satellites for advanced communications. This research effort sets out to prove if a high bandwidth signal can be generated by using low-cost SDRs. The SDR receivers will each receive different sub-bands of the transmitted signal with the goal of the meshing the received signals to form a high bandwidth signal.
