The performance of Bit-Interleaved Coded Modulation with Iterative Decoding (BICM-ID) depends strongly on the applied mapping. We analyse the use of extended mapping schemes with more than one label per signal point: Assuming a fix signal constellation and a constant number of information bits per symbol, the increase in label length results in an ambiguous(More)
—In Mars exploration tasks, robotic swarms containing multiple autonomous units are efficient and robust against hazards in the mission. However, when the swarm travels significantly far away from the base, it is not sufficiently reliable to use the local map generated during the exploration alone to return. We propose a return-to-base navigation system for(More)
A new vector phase-locked loop (PLL) for joint tracking of carrier phase from all satellites on multiple frequencies is presented. It increases the robustness to ionospheric scintillations, carrier phase multipath and interference from jammer. The tracking error is split into a position error, a clock offset, ionospheric, and tropospheric errors which are(More)
BIOGRAPHIES Patrick Henkel studied electrical engineering and information technology at the Technische Universität München, Germany and thé Ecole Polytechnique de Montréal, Ca-nada. He is a Ph.D. student at the Institute of Communications and Navigation at TUM since 2005 and focuses on robust ambiguity resolution for precise carrier phase positioning with(More)
Preface Currently, the Global Navigation Satellite Systems (GNSS) GPS and GLONASS are modernized and new GNSS such as Galileo and Compass are developed. The modernization of GPS includes an additional signal on L5 which lies in an aeronautical band. This will enable a dual frequency positioning on board an aircraft and an elimination of the dispersive(More)
