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 January 24, 2002 NSF Workshop on Context-Aware Mobile Database Management Providence, Rhode Island

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 NSF workshop on “Tetherless T3 and Beyond”

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,…)
