Andreas Spanias is professor in the School of Electrical, Computer, and Energy Engineering at Arizona State University (ASU). He is also the Founder and Director of the SenSIP Center and Industry Consortium (NSF I/UCRC). His research interests are in the areas of adaptive signal processing, speech processing, and audio sensing. He and his student team developed the computer simulation software Java-DSP (J-DSP - ISBN 0-9724984-0-0). He is author of two text books: Audio Processing and Coding by Wiley and DSP: An Interactive Approach. He served as Associate Editor of the IEEE Transactions on Signal Processing and as General Co-chair of IEEE ICASSP-99. He also served as the IEEE Signal Processing Vice-President for Conferences. Spanias is co-recipient of the 2002 IEEE Donald G. Fink Paper Prize Award and was elected Fellow of the IEEE in 2003. He served as Distinguished Lecturer for the IEEE Signal Processing Society in 2004.

Abstract

Multidisciplinary Java-DSP Phase 3 Project; Development for Wireless Devices This invited paper to the NSF grantees session of ASEE 2012 presents recent extensionswith the NSF sponsored project aimed at developing, disseminating and assessing the J-DSPonline software [1]. By involving several universities and several disciplines, this project hasenabled the use of J-DSP in several courses. The phase 3 multidisciplinary NSF TUES (CCLI)project is a collaborative project involving Arizona State University (ASU), Johns HopkinsUniversity (JHU), University of Washington Bothell (UWB), and Prairie View A&M University(PVAMU). This project also involves sponsored partnerships with Rose-Hulman Institute ofTechnology (RHIT), University of New Mexico (UNM), and University of Cyprus (UCY). As part of the Phase 3 TUES project, we have developed a simulation environment thatwill enable students to perform laboratory exercises using modern mobile devices and tablets.The project focuses on wireless devices such as the Apple iPhone and the Google Android andthe compatible tablets. Our hypothesis is, due to the pervasive nature of these new “gadgets”,education applications for mobile devices may stimulate student interest in addition to offeringconvenient access and new capabilities. This paper will describe a portable signal processinglaboratory for the Android platform. This software is intended to be an educational tool forstudents and instructors in DSP and signals and systems courses. The Phase 3 group at ASU haspreviously developed an iPhone/iPad DSP simulation application reported in [2]. We have nowcreated a more comprehensive software with labs for the Android system that will also addressapplications in other close disciplines as well such as earth systems. The development ofAndroid JDSP is carried out using the Android SDK, which is a Java based open developmentplatform. The proposed application will offer basic DSP functions for FFT, filtering andfrequency domain analysis, with a convenient graphical user interface. Furthermore, a stand-alone demo function that animates the process of continuous/discrete-time convolution will bedeveloped. The description of the functions, laboratory exercises and assessment results will alsobe presented in the full paper. An assessment of our hypothesis will also be reported in detail.[1] A.
