Abstract

We describe a testbed that is being developed for the evaluation of demodulation algorithms in communication systems. This testbed is intended to provide a research tool in the area of signal demodulation and is built around easily programmable, general purpose and digital signal processors. A variety of analog and digital modulations can be evaluated in real and non-real-time scenarios and under different channel conditions ranging from intersymbol interference to modulated or unmodulated co-channel interference. Testbed architectural and design details are presented along with preliminary results of our algorithm development and testing program.
