Advanced Algebraic Concepts for Efficient Multi-Channel Signal Processing (2013)
Abstract / truncated to 115 words
Modern society is undergoing a fundamental change in the way we interact with technology. More and more devices are becoming "smart" by gaining advanced computation capabilities and communication interfaces, from household appliances over transportation systems to large-scale networks like the power grid. Recording, processing, and exchanging digital information is thus becoming increasingly important. As a growing share of devices is nowadays mobile and hence battery-powered, a particular interest in efficient digital signal processing techniques emerges. This thesis contributes to this goal by demonstrating methods for finding efficient algebraic solutions to various applications of multi-channel digital signal processing. These may not always result in the best possible system performance. However, they often come close while being ... toggle 8 keywordsalgebra – multi-dimensional signals – tensor decomposition – direction of arrival estimation – harmonic retrieval – two-way relaying – channel estimation – amplify and forward
