The SpectrumWare project is applying a software oriented
approach to wireless communication and distributed signal processing. Advances
in processor and analog-to-digital conversion technology have made it possible
to implement virtual radios that directly sample wide bands of the downconverted
RF spectrum, and process these samples in application software. The elimination
of dedicated hardware introduces tremendous flexibility into a wireless
communications system. However, our approach goes further than the software
implementation of traditional signal processing functions. We use processor
and network memory to temporally decouple the sample streams from the software
modules so that the bulk of the processing can be realized within virtual
time programming environments. Decoupling relaxes the temporal constraints
on the processing algorithms and their execution. The testbed will be used
to implement a wireless communication system and to experiment with other
forms of transducer-based information appliances.
