Project Description: With support from MHI, these M.S. students from the Ming Hsieh Department of Electrical Engineering have formed Team VISIONary to compete in the Cornell Cup USA, presented by Intel, a nation-wide university embedded design competition. Team VISIONary has proposed developing a hardware prototype and signal processing algorithms for a Local Position Detection System (LPDS) with a Navigation System (NS) to navigate the blind in a complex indoor environment. The LPDS will use local mapping and image processing to triangulate the user’s position and direct the user to his desired location, while the navigation system will utilize obstacle avoidance algorithms to ensure safe navigation to his desired destination. This composite system will first be tested in a closed environment that effectively simulates real life indoor navigation scenarios, and then it will be used by a number of visually impaired people in their daily routines.



Title: Distributed Multiuser MIMO on a Large-Scale Software-Radio Testbed
Presenters: (left to right) Ryan Rogalin, Horia Vlad Balan, Antonios Michaloliakos

Advisors: Konstantinos Psounis and Giuseppe Caire

Project Description: Multiuser MIMO is leaving the theoretical stage and moving towards practical deployment. Current implementations are limited to single access points, since synchronizing symbol timing and phases across different access points has been traditionally seen as too difficult. In this demo we will present the first practical system realization that disproves this idea. We have managed to synchronize different access points within picoseconds in order to provide phase consistency across different transmitters. Using the resulting spatial diversity gains, we transmit to multiple users with full spatial multiplexing, obtaining large pre-log capacity gains.
