@inproceedings{302, author = {Sandor Szilvasi and Benjamin Babjak and Akos Ledeczi and Peter Volgyesi}, title = {Software-defined radio for versatile low-power wireless sensor systems}, abstract = {Traditional wireless sensor network architectures are based on low-power microcontrollers and highly integrated short range radio transceiver chips operating in one of the few ISM bands. This combination provides a convenient and proven approach to design and build inexpensive sensor nodes rapidly. However, the black box nature of these radio chips severely limit experimentation and research with novel and innovative technologies in the wireless infrastructure. Our team previously proposed a revolutionary architecture for wireless nodes based on Flash FPGA devices. This paper shows the rst results of our work through the implementation and evaluation of a simple baseband FSK modem in the SmartFusion FPGA fabric. We also demonstrate how we could leverage existing software radio projects to use the baseband modem in a wide range of radio frequency bands.}, year = {2011}, journal = {International Conference on Digital Information Processing and Communications}, month = {07/2011}, address = {Ostrawa, Czech Republic}, }
