The exponential growth of data rates for mobile applications is driven by progress in both the domains of communication algorithms and VLSI technology. A communication technology promising a continuation of exponential data rate growth is MIMO which uses multiple antennae at both receiver and transmitter and transmits multiple data streams at the same time over the same frequency band. In this presentation we address the various aspects of the MIMO technology from a receiver perspective. To motivate optimal receiver algorithms we show that an optimal receiver achieves the same error rate at a 13dB lower SNR compared to the simplest low complexity algorithm.
We derive the optimal ML receiver algorithm which is clearly infeasible but serves as the basis for engineering approximations which are economically realizable. In the main part of this talk we discuss the design, and its corresponding design methodology, of the world-wide first VLSI implementations of optimal iterative MIMO receivers. Working silicon has been fabricated in 65nm technology and has been fully tested in 2012. It is the result of collaboration between researchers of ETHZ, EPFL and RWTH Aachen. The main message 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. We will discuss the trade-offs between communication performance and architectural efficiency metrics, such as area- , energy efficiency and flexibility/programmability.
