Abstract:

High speed wireless mobile communication systems have become increasingly important in battlefield commandcontrol and in sensor network systems for national defense and security. The project investigates advanced design of bandwidth efficient retransmission diversity in multi-input multi- output MIMO wireless communication systems. We develop optimization techniques in hybrid ARQ and MIMO precoding for robust, progressive, adaptive, and scalable diversity. We focus on OFDM as the underlying broadband signal modulation. We present new frameworks for the novel integration and optimization of bandwidth efficient and scalable ARQ protocols with robust precoding and other MIMO techniques in broadband OFDM wireless communication systems. We design bandwidth and power efficient transceiver technologies in full integration with new HARQ designs for the performance improvement of end user applications. Overall, our goal is to develop design methodologies of broadband wireless MIMO communication systems for military operations. The new techniques developed in this project can be applied in wireless networks for military operations to significantly improve performance with limited bandwidth and power resources encountered by defense units.
