UMBC 1 Adaptivity With and Within Physical Layer for Pervasive Computing Tülay Adalι University of Maryland Baltimore County Department of CS and Electrical Engineering Baltimore, MD 21250 adali@umbc.edu January 24, 2002 NSF Workshop on Context-Aware Mobile Database Management Providence, Rhode Island

2. UMBC 2 Significant advances in basic research to provide a foundation for designing high information-capacity wireless communication systems for full mobility will require synergistic, multidisciplinary research efforts encompassing a breadth of communications functions from the physical through application layers. 1998 NSF workshop on “Tetherless T3 and Beyond”

3. UMBC 3 MCM for Next Generation Wireless Next generation wireless systems are characterized by their high demand on adaptability to a wide range of channels and traffic conditions and patterns Multi-carrier modulation (MCM) is an attractive candidate for satisfying this demand (DMT, OFDM, MC-CDMA,… ) Optimization of MCM functions can be handled together with network and application functions (PAR, channel modeling,…)
