| الوصف: | In this work, a comprehensive analysis of a competitive and novel, high-precision local positioning system in the 5.8 GHz ISM band is presented. The RESOLUTION platform is built around a secondary-radar FMCW positioning system, supported by a commercial communications solution. The modular and flexible design of the platform allows for the support of various topologies and protocols, which is of supreme interest with regard to the very diverse application fields local positioning can serve. To gain an impression of performance figures with an eye towards actual product deployment, a cross-layer simulation tool was developed. This software allows for analysis of both physical layer properties and network dynamics which occur when multiple receivers are served within a fixed infrastructure. The signal theoretical foundations of secondary FMCW radar are well established. With regard to this, research on the physical layer is limited to selected effects, with special attention on multipath propagation, which constitutes by far the largest error source. For comparative evaluation, both a model derived from system-specific measurements as well as a standardized model following IEEE 802.15.4a were integrated into simulation. The performance of MAC layer algorithms for multi-user management have been analyzed along the most relevant parameters, such as time-to-fix, update rate, infrastructure utilization and efficiency. The seamless design of the physical and MAC layer simulators allows for complete integration and cross-layer optimization of the platform. Exemplary simulation results are provided. Access procedures derived from known communication models and adapted for the specific needs of positioning systems are described. Utilization of these methods allows for optimal system deployment according to specification parameters. This thesis constitutes an authoritative reference for the performance of the RES local positioning system. Novel algorithms with cross-platform effects are investigated. The innovative ... |
