Abstract
The evolution of satellite communication systems for the design of both the satellite's communication payload and the ground-station are towards the implementation of such systems using the Software Radio (SR) technology. This paper focuses on a key element of the SR, that is, the wideband front-end which still poses the greatest technological challenge for design and proliferation of SR. In particular, we look at the front-end architecture of wideband receivers, outline the key aspects of the design of such front-end systems, specify the performance metrics associated with their design, present an architecture of a promising wideband analog to digital converter, and finally present the results of our design, implementation, and test campaign of a prototype PC-based SR system.
