Field Trial and Experimental Results of MIMO Systems for Non-Commercial Applications

Professor Babak Daneshrad


The invention, over a decade ago, of multiple-input multiple-output (MIMO) techniques by Bell Labs Stanford, and other researchers spawned a tidal wave of research that continues to this date has resulted in well over 80,000 publications focused on some aspect of multi-antenna MIMO communications. A great many of these works are theoretical in nature and show the tremendous potential of MIMO based communications.
In this talk we present a series of experimental results that look to quantify the performance of a MIMO link in the following scenarios:

  •  Ground to ground communications in urban and open field settings
  •  Air to ground links from Tier 3 UAVs and commercial jetliners
  •  Robotic teleoperations in support of military and law enforcement
  •  Interference mitigation
  •  Urban mesh networking

Some examples of MIMO gains documented via field testing include:

  •  lower transmit power for the same distance and throughput
  •  Increase in coverage area in urban multipath rich environments
  •  Successful communications below deck through multiple levels
  •  Support for high fidelity video from UAS and UGVs
  •  Range increase for air to ground communications
  •  Suppression of wideband interference/jamming
  •  Much improved spectral efficiency.

The talk will conclude with a live demonstration of a MIMO radio showing the energy and spectral efficiency of a MIMO system.


Biography: Babak Daneshrad is a Professor with the UCLA Electrical Engineering Dept., and a Co-founder of Silvus Technologies, Inc. His research interest are multi-disciplinary in nature and include system and VLSI de-sign for wireless communications. He is the recipient of the 2005 Okawa Foundation award, a co-author of the best paper award at PADS 2004, and was awarded first prize in the DAC 2003 design contest. He is the benefi-ciary of the endowment for “UCLA-Industry Partnership for Wireless Communications and Integrated Systems”. In Jan. 2001 he co-founded Innovics Wireless a company focused on developing 3G-cellular mobile terminal anten-na diversity solutions and in 2004 he co-founded Silvus Communications. From 1993 to 1996 he was a member of technical staff with the Wireless Communications Systems Research Dept. of AT&T Bell Laboratories where he was involved in the design and implementation of systems for high-speed wireless packet communications
