Abstract

Advances in IC technology have increasing allowed for the placement of the digital signal processing closer to the antenna in wireless communication devices. Another consequence of the broadening of digital processing in modern communications is the desire to use wholly programmable devices to enable the complete modification of signal demodulation algorithms after the A/D. The technology is evolutionary in that it potentially allows for the over the air software downloading of the most advanced protocols and algorithms directly in the field. Furthermore, SDR mobile devices can rapidly adapt to any signaling environment, anywhere (i.e. take it with you devices).

In this discussion, we present an overview of SDR architectures, algorithms, properties, and open areas of research.
