Overview: 

An easy and active sharing of information is a main success factor of a data-driven world, where all individuals have become active participants. In the data-driven world, mobile devices such as smart-phones, tablets, and wearables have become indispensible to users for their everyday life. Major enablers of this data-driven world are advances in cellular and connectivity technologies which support wireless capacity enough to accommodate data traffic surge. Cellular mobile communications systems have been evolving, is evolving, and will evolve continuously. All cellular systems have been unified into LTE system which introduces new features without pause such as D2D (Device to Device), LAA (Licensed Assisted Access), and FD-MIMO (Full Dimension - MIMO). Therefore, in the development of cellular terminal modem chipsets, one of the most important things is to implement new features on time and to respond market requirements. In other sides, in order to prepare mid/low end markets which become dominant markets, various types of integration of major components of smart-phone, such as application processor, baseband modem, RF device, power management, and wireless connectivity, has been attempted to make cost reduction. Furthermore, it becomes more important to provide hardware and software turn-key solutions.

Profile: 

Chaehag Steve Yi received the B.S., M.E., and Ph.D. degrees in Electronics Engineering from Seoul National University, Seoul, Korea, in 1989, 1991, and 1996, respectively. He worked for the Electronics and Telecommunications Research Institute (ETRI), Taejon, Korea, on a part-time basis in 1992. He has worked for Samsung Electronics Co., Ltd. since 1993. He is currently a Master of Samsung Electronics and participates in the development and commercialization of cellular terminal modem chipsets. His research interests include digital communication theory, mobile communication systems, wireless connectivity, joint RF and baseband optimization, software-defined radio processor, and cellular modem architecture design.
