Performances of EM Channel and Shannon Theory Dau-Chyrh Chang Lorom Institute of New Products Research and Development, Lorom Group |
Abstract: The Shannon theory, as shown in the following equation, is important in nowadays’ digital data communication. The Shannon theory describes the maximum data rate (or throughput) in channel is related to the number of parallel channels M, effective bandwidth B, signal power S, external noise power and internal noise power. This talk will describe the relationship between all the parameters in Shannon theory and the electromagnetic (EM) performances. The EM performances will include the characteristics of wireless channels (such as antenna and wireless propagation, etc.) and wired channels (such as RF cables, microstrip, stripline, and digital high speed cables, etc.). From the EM channels point of view, the important parameters of EM channels and their measurement techniques will also be discussed in this talk.
Biography:
Prof. Chang, IEEE Life Fellow and EMA Fellow, is the Chief Scientist and Dean at Loom Institute of New Products Research and Development. He obtained his BS degree and MS degree from Chung-Cheng Institute of Technology, and Ph.D. degree in Electrical Engineering from University of Southern California. He spent 25 years in antenna R&D at CSIST. For 17 of these years, he served as director of antenna section. During his employment at CSIST, he developed reflector antennas, phased array antennas, slot array antennas, communication antennas, and various antenna test ranges. In 1998, he left his post as director of the antenna section to become Dean of the Engineering School at Da-Yeh University. He had been invited to be the Dean of College of Electrical and Communication Engineering at OIT (Oriental Institute of Technology) in 2006. He has been the Chair Professor and Director of CRC (Communication Research Center) at OIT from 2006 to 2016. He has been established four laboratories during executing various research programs, lab of hybrid antenna near field antenna test range, lab of TRP/TIS communication measurement system, lab of EMC, and lab of EM simulation, at CRC of OIT. Except for various kinds of antenna research, Prof. Chang is also focus on the research on SI (Signal Integrity) with the funding support from Lorom Group. Since August 1, 2016, he changes his career from OIT to Lorom Institute of New Products Research and Development, Lorom Group. He has published over 400 papers at technical journals and technical conferences. Except for the technical papers, he also has more than 20 patents.
Prof. Chang established the IEEE AP-S Taipei Chapter and as the first Chair in 2001, Chair of IEEE MTT-S Taipei Chapter and President of Chinese Microwave Association in 2000-2002. He has been the General Chair of CSTRWC2001, CSTRWC2008, ISAP2008, ICONIC2009, AEM2C2010, CSQRWC2012, PIERS2013, IEEE MTT-S IMWS-Bio 2015. He is the founding Chair of IEEE iWEM since 2011 and General Chair or Co-General Chair of IEEE iWEM. He received many excellent research awards when he was at CSIST, DYU, and OIT.
