Wireless Cooperative Networks: Self-Configuration and Optimization. Final Report May 2007-July 2010

摘要

Cooperative signal processing is a promising technique to enhance system performance by employing virtual antenna arrays. In communications, cooperative transmission exploits space diversity via spatially separated relay nodes. Performance of such systems can be further improved by resource optimization. In this research, we investigated various factors influencing the resource optimization solutions and results in terms of the system error performance and throughput. Partly inspired by the benefits of cooperative communications, cooperative sensing is also drawing increasing interests lately. In such systems, a particularly critical issue is the waveform optimization among the cooperative nodes. In this direction, we developed the optimum and robust waveform designs respectively, and established the intrinsic connections between the mutual information (MI and mean square error (MSE)) measures in the sensing context. The sensitivity analysis for the optimum designs is also carried out.
