University of Southern California WiDeS - Wireless Devices and Systems Group The USC Andrew and Erna Viterbi School of Engineering USC


Welcome to WiDeS, the Wireless Devices and Systems group at the USC Viterbi School of Engineering. We are a research group dedicated to research that is both scientifically challenging and practically relevant. The main emphasis of our research is on the physical layer of wireless communications, but we also deal with overall wireless systems integration, wireless positioning and radar, cross-layer design for wireless sensor networks.

Some parts of the site are still under construction - please bear with us while we work on it, and check back for updates!

Possible openings for PhD students in the area of channel measurement, estimation, and modeling at the WiDeS group at USC

The WiDeS group (Wireless Devices and Systems, head: Prof. Andy Molisch) is one of the world's leading groups in the measurement and modeling of wireless propagation channels. Using worldwide-unique equipment, we are performing measurements in massive and distributed MIMO systems, millimeter-wave systems, and vehicle-to-vehicle channels, perform high-resolution evaluations, and develop channel models that have formed the basis for international standardization and are used worldwide. Our work is based on the principle that equipment construction, experiment design, signal processing for channel parameter extraction, and channel modeling all have to go hand in hand to get the best possible results. You can find some more information at  (please note that the website is about two years old - we have obtained a number of exciting results in the meantime - but you will get a general idea).

To further expand our activities in the area, we are expanding our team. If you want to be at the forefront of wireless propagation research and are interested in one or more of the following topics:

* RF system design, experiment design, ray tracing, channel modeling

* signal processing with emphasis on maximum-likelihood estimators, iterative estimation algorithms

then consider applying for a PhD position at WiDeS, and fill out the form at

Summer is here!

The semester has passed quickly, finals are over, and WiDeS is starting into the summer. A number of our students will be on internships, at such places as Bell Labs, Intel, and DoCoMo. Others will enjoy the possibility of concentrating on their research even more – plus some well-deserved vacations. From WiDeS to all of our affiliates and friends, best wishes for a good summer.

Fast and Accurate Synchronization in the “Blink” of an Eye (USC Press Release):
USC Viterbi Professors improve wireless clock synchronization accuracy tenfold London, June 9, 2015 –

A USC press release draws attention to one of WiDeS’ (in collaboration with Prof. Hashemi) significant research results: experimentally showing synchronization of wireless networks with nanosecond precision, and developing algorithms that allow scaling this result to very large networks.

Our philosophy is to bridge the main chasms in today's wireless research
  • theoretical vs. industrial: there is often the misconception that theoretical work cannot be practically relevant. But experience from advanced system design shows that in order to build systems that not only work, but are also better than the competition, new research, dedicated to the specific goals of the system, is required. Members of the group have many years experience in industrial research labs and standardization of wireless systems.
  • theoretical vs. experimental: theoretical breakthroughs are often made on paper, but they have to be verified by experiments - that is one of the basic tenets of science, though it is sometimes forgotten even in engineering research. Careful design of experiments, knowledge of best measurement procedures and innovations in the evaluation methods of large-scale measurements are all vital components of today's wireless research.
  • communication theory vs. antennas/propagation. 


The WiDeS group was founded in January 2009 by Andy Molisch, when he joined the USC Viterbi School of Engineering, after a career in both industry (AT&T Bell Labs, Mitsubishi Electric Research Labs, Research Center for Telecommunications Vienna), and academia (Lund University, Technical University Vienna). WiDeS is a part of the Communications Sciences Institute of the Department of Electrical Engineering at USC, and is affiliated with the ULTRA-Lab at USC.
