The receivers treat the reflected paths also reaching the receiver antenna as disturbance which has to be suppressed. Multipath affects the tracking accuracy by resulting in a degeneration of the S-curve of the DLL (delay locked loop). Nowadays the future European systems GALILEO and GPSIIF/III with two new signals are on the way to the market and it is time to think about new receiver structures. Therefore we investigated if it is possible to use multipath for navigation constructively.}, author = {Bischoff, Renke and Haeb-Umbach, Reinhold and Schulz, Wolfgang and Heinrichs, Guenther}, booktitle = {IEEE 55th Vehicular Technology Conference (VTC 2002 Spring)}, keyword = {combined GALILEO/UMTS receiver, delay locked loop, delay lock loops, DLL, Global Positioning System, GLONASS, GPS, GPSIIF/III, mobile satellite communication, multipath channels, multipath receiver structure, radio receivers, RAKE receiver, S-curve}, pages = {1844--1848 vol.4}, title = {{Employment of a multipath receiver structure in a combined GALILEO/UMTS receiver}}, doi = {10.1109/VTC.2002.1002940}, volume = {4}, year = {2002}, } @inproceedings{11808, abstract = {Current location methods for cellular communication systems TOA and E-OTD exploit time delays and time differences of various base station signals measured in a mobile phone to determine its location. These methods assume line-of-sight (LOS) connections to all utilized base stations. Since mobile radio channels are mainly characterized by scattered propagation paths and non-line-of-sight (NLOS) propagation, bias errors occur when measured time delays and time differences are utilized in position calculation algorithms. In this paper, the distribution of the time error due to NLOS propagation is estimated based on the channel model proposed in [1]. In combination with actual channel measurements in [2] the NLOS time error and its probability distribution function is estimated. With this information being determined for each received signal, position calculation algorithms can utilize the reliability information to enhance positioning accuracy. [1] L. J. Greenstein, V.

Hybrid CPUs that combine standard CPU cores with reconfigurable coprocessors are an important subclass of CSoCs. With partially reconfigurable FPGAs, coprocessors can be loaded on demand while the CPU remains running. However, the lack of high-level design tools for partial reconfiguration makes practical implementations a challenging task. In this paper, we introduce a design flow to implement hybrid processors on Xilinx Virtex. The design flow is based on two techniques, virtual sockets and feed-through components, and can efficiently generate partial configurations from industry-quality cores. We discuss the design flow and present a fully operational audio streaming prototype to demonstrate its feasibility. }, author = {Dyer, Matthias and Plessl, Christian and Platzner, Marco}, booktitle = {Proc.
