A Metaheuristic Framework for Optimized HAPS-Aided Localization in Urban Areas
Hongzhao Zheng, Mohamed Atia, Halim Yanikomeroglu
High-altitude platform stations (HAPS), originally designed for communication services, can also provide structured signals of opportunity (SoOP) to augment the global navigation s…
Optimized Deployment of HAPS Systems for GNSS Localization Enhancement in Urban Environments
Hongzhao Zheng, Mohamed Atia, Halim Yanikomeroglu
While high altitude platform stations (HAPS) have been primarily explored as network infrastructure for communication services, their advantageous characteristics also make them pr…
Realistic Channel and Delay Coefficient Generation for Dual Mobile Space-Ground Links - A Tutorial-
Hongzhao Zheng, Mohamed Atia, Halim Yanikomeroglu
Channel and delay coefficient are two essential parameters for the characterization of a multipath propagation environment. It is crucial to generate realistic channel and delay co…
Synthetic Waveform Generation for Satellite, HAPS, and 5G Base Station Positioning Reference Signal Using QuaDRiGa
Hongzhao Zheng, Mohamed Atia, Halim Yanikomeroglu +1
Waveform generation is essential for studying signal propagation and channel characteristics, particularly for objects that are conceptualized but still need to be operational. We…
