DESCRIPTION:Dr. Heinrich Meyr.  Bio: Dr. Meyr received his M.Sc. and Ph.D
 . from ETH Zurich\, Switzerland. He spent over 12 years in various researc
 h and management positions in industry before accepting a professorship in
  Electrical Engineering at RWTH Aachen.  Presently Dr. Meyr is a visiting
  professor at the LSI of EPFL.  During the last 40 years\, Dr. Meyr has w
 orked extensively in the areas of communication theory\, digital signal pr
 ocessing and CAD tools for system-level design. Dr. Meyr has received seve
 ral IEEE best paper awards. He is a-Life Fellow IEEE. Dr .Meyr has a dual 
 career as entrepreneur. He has founded several successful companies. The l
 ast company he has cofounded in 2001 was  LisaTek which merged with CoWar
 e in 2003.  In 2010  CoWare was acquired by Synopsys.\nThe exponential g
 rowth of data rates for mobile applications is driven by progress in both 
 the domains of communication algorithms and VLSI technology. A communicati
 on technology promising a continuation of exponential data rate growth is 
 MIMO  which uses multiple antennae at both receiver and transmitter and t
 ransmits multiple data streams at the same time over the same frequency ba
 nd. In this presentation we address the various aspects of the MIMO techno
 logy from a receiver perspective. To motivate optimal receiver algorithms 
 we show that an optimal receiver achieves the same error rate at a 13dB lo
 wer SNR compared to the simplest low complexity algorithm.\nWe derive the 
 optimal ML receiver algorithm which is clearly infeasible but serves as th
 e basis for engineering approximations which are economically realizable.
   In the main part of this talk we discuss the design\, and its correspon
 ding design methodology\, of the world-wide first VLSI implementations of 
 optimal iterative MIMO receivers. Working silicon has been fabricated in 6
 5nm technology and has been fully tested in 2012. It is the result of coll
 aboration between researchers of ETHZ\, EPFL and RWTH Aachen. The main mes
 sage of the talk will be that the design of advanced communication systems
 - with emphasis on system- mandatorily requires to jointly considering the
  multidimensional design space comprising algorithm –and architecture. W
 e will discuss the trade-offs between communication performance and archit
 ectural efficiency metrics\, such as area- \, energy efficiency and flexib
 ility/programmability.
