Mario Magaña Associate Professor School of EECS Oregon State University Mitigation of Computer Platform Random Interference The trend of electronic systems towards higher integration and higher performance has also brought new challenges to radio receiver design. The decrease of switching times accompanied by the increase of clocks and data rates, interconnection speeds contributes to improve the overall system performance. At the same time, they also affect wireless communications due to an increment of the emissions of electromagnetic radiation on the radio bands. We have analyzed the main contributors to the noise generated by the emissions known as platform noise and some on their main features are presented. Statistical analysis of platform noise measurements done on the 2.4 GHz band have shown that this type of noise is Non-Gaussian. Motivated by this fact, a statistical model that is consistent with the physical characteristics of the process rather than only on data fitting has been derived. The model is closely related to the one derived for modeling of clutter in radar and it has been found to agree with experimental data. Its analysis will be also presented. The accuracy of the noise model is of paramount importance, as it allows us to design radios that are immune to it. Finally, simulations of the impact on the radio performance of platform noise in terms of the Bit Error Rate (BER) for OFDM systems are presented. Biography Mario E. Magaña (IEEE M’78–SM’94) received his BS degree in electrical engineering from Iowa State University in 1979, his MS degree in electrical engineering from the Georgia Institute of Technology in 1980, and his PhD, also in electrical Engineering, from Purdue University in 1987. He is currently an Associate Professor of Electrical Engineeringand Computer Science at Oregon State University in Corvallis, Oregon, USA and a Fulbright Professor at the National University of La Plata, Argentina. He has also been an invited Researcher/Lecturer at the Universities of Ulm and Stuttgart, in Germany, and at the Technical University of Catalunya in Barcelona, Spain. Prior to joining the faculty at Oregon State University in 1989 and before starting his doctoral studies at Purdue University, he spent several years working in the Analysis and Technology Group of the Communications Systems Division at the Harris Corporation in Melbourne, Florida, in the Flight Control Systems Research Unit at the Boeing Company in Seattle, Washington, and at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Dr. Magaña is a senior member of the IEEE, a NASA faculty fellow and a member of HKN, the electrical engineering honorary society. He is the author of more than 80 technical and scientific papers, and has written two books on network coding and structural control. His current areas of research are in the fields of mobile wireless communications, automatic control applications and mathematical modeling of biological systems. _______________________________________________ Colloquium mailing list [email protected] https://secure.engr.oregonstate.edu/mailman/listinfo/colloquium
