Speaker: Dr. Earl McCune, RF Communications Consulting, Panasonic Technology Fellow (ret.), IEEE MTT Distinguished Microwave Lecturer 


Achieving energy-efficient “Green” communications requires the cooperation of all blocks within a communication system.  This includes the digital and analog basebands, the transmitter, the receiver, the protocol, and most importantly the signal modulation selected.  Optimizing any one of these, which is by far the most common approach, leaves the entire system far from its optimum efficiency.  But when the entire system is jointly designed for optimum efficiency in the presence of all  communication throughput requirements, significant energy savings relative to conventional design can be realized.  These techniques hold equally for wireless and wireline communication channels.

This presentation begins with the fundamental physics of total energy efficiency, and discusses the resulting circuit operating aspects necessary to achieve the best available efficiency.  Then the system aspects of modulation properties and protocol are derived that are necessary to allow access to the derived circuit optimal efficiencies.  Collection of all these results into a set of joint optimization parameters is then presented as the fundamental requirements for achieving Green communications systems.

Bio for Earl McCune:

Earl received his Bachelors, Masters, and Doctorate degrees at UC Berkeley, Stanford, and UC Davis respectively.  His experience in RF circuits, signals, and systems goes back more than 40 years.  Within this career he has founded two Silicon Valley startups, the first one doing modulated direct digital frequency synthesis in 1986 which merged with Proxim in 1991.  The second start-up, Tropian, did switch-based RF transmitters from 1996 and was acquired by Panasonic 10 years later.  He retired from Panasonic in 2008 as a Managing Director and Corporate Technology Fellow.  He has 76 issued patents in the USA.  He is a double author with Cambridge University Press, first with Practical Digital Wireless Signals, and also with Dynamic Power Supply Transmitters.  He is an appointed IEEE MTT Distinguished Microwave Lecturer since 2013. Dr. McCune has been an invited speaker at RWS, PA Symposium, WAMICON, ISCAS, WCNC, and ISSCC.  He has served on the CICC technical program committee (TPC) since 2000, and also served on the TPC for RWS and the PA Symposium.  He is a regular reviewer for IEEE Journal of Solid State Circuits, Transactions on Microwave Theory and Techniques, and the Transactions on Circuits and Systems.
