Traditional wireless security schemes neglect the unique properties of the wireless channel. Exploiting physical layer can significantly enhance the conventional security schemes. However, the robustness and bit mismatch rate of current physical-layer-based schemes still need to be improved. Conventional two thresholds quantization is not stable when inserting or removing intermediate objects between...
The potential interference of ultra wideband (UWB) on existing narrowband wireless communication systems must be analyzed before it is applied, so the paper uses a method based on the physical layer model to analyze the compatibility of direct-sequence ultra wideband (DS-UWB) and multi-band ultra wideband (MB-UWB) on several narrowband victim systems. Based on the physical layer models of PAM-DS-UWB...
Aiming at the effect of ultra wideband (UWB) system for the potential victim systems on UWB operating frequency band, using the entire physical layer model method, this paper studies the interference of direct-sequence ultra wideband (DS-UWB) and multi-band ultra wideband (MB-UWB) on these victim systems. Depended on the physical characteristics of UWB and these victim systems, the entire physical...
