Space-Time Processing for Tactical Mobile Ad-Hoc Networks
Abstract
Recent developments in communication systems technology promise to greatly improve the performance of point-to-point communications for both commercial and tactical networks. In this project we will address the challenging question of how these technological developments can best be exploited in a tactical networking context, where signal interference and channel uncertainty issues have a tremendous impact on end-to-end system performance. Tactical applications pose unique requirements for the network, including decentralized control to eliminate single points-of-failure, vulnerability to jamming and electronic warfare, and mission critical latency bounds for end-to-end data delivery. Moreover, a tactical network is generally composed of mobile nodes and the routing protocols must deal with a range of node mobilities and time varying channel conditions. This project is focused on the design of ad-hoc networking architectures that utilize MIMO transmitters and receivers at each node. This program will evaluate tradeoffs in waveform design, beamforming, space-time coding, channel state estimation, and receiver design in order to define the best way to utilize time-frequency-and spatial diversity to improve the robustness, capacity, and quality of service of a tactical mobile ad-hoc network.
