KEYNOTE ADDRESS I Title: Trends in Software Defined and Cognitive Radios Dr. Ajit T Kalghatgi Director (R&D), BEL, Bangalore. Email:
[email protected] Abstract: Modern day communication technologies provide for effective transmission and reception of high data rate multi-media information over constrained channels. Migration from conventional Analog radio to packetized digital radios has enabled networked, mobile broad band access over demanding terrains. Dependence on standards driven & protocol dependant point-point & point-multipoint mobile Adhoc network has given rise to the need for platform agnostic software driven customizable radios. This has led to proliferation of a range of Software Defined Radios & Software Defined Networks. Challenges associated with optimal resource management of spectrum, user bandwidth driven applications & minimization of cost, weight and power requirements has led to the development of smart, intelligent or Cognitive Radios. This talk presents the trends and the challenges associated with the development, engineering & deployment of configurable, smart communication technologies associated with SDR & Cognitive Radios, Spectrum sensing and deployment of Cognitive Radios. Curriculum Vitae: Dr. Ajit T Kalghatgi is currently Director (R&D) of Bharat Electronics Ltd. He was till recently Chief Scientist at BEL’s Central Research Laboratory (CRL). He has more than 30 years of Experience in the field of RF & Microwave Engineering. After graduating from Mysore University with B.E in Electronics & Communications, he completed his M.Tech in Microwave & radar engineering from IIT, Kharagpur and Ph.D., from Leeds University, UK. He worked in Avionics Design Bureau of HAL Hyderabad as Design Engineer responsible for Microwave Front-ends & IFF transceiver. He was with the University of Leeds, UK from 1988 to 1993 for his Ph.D as a Commonwealth Research Scholar and later as a Post-Doctoral Fellow.
