Channel Modeling and Characteristics for High Altitude Platform Stations Communication System

Channel Modeling and Characteristics for High Altitude Platform Stations Communication System

The research on high altitude platform stations (HAPS) system and HAPS mobile high-speed communication system is still in its infancy. In the absence of valid description of HAPS mobile channel characteristics, there are few special research on signal transmission and data processing technologies in HAPS mobile communications. When analyzing the angular spectrum of multipath scattering distribution in HAPS mobile channel, the plane wave assumption of ground wireless mobile channel is no longer valid, and it is necessary to consider the extension of the elevation and azimuth at the mobile terminal. The HAPS mobile channel characteristic system is constructed by software simulation, which provides channel models and parameters in different environments for the broadband HAPS mobile communication system and its ground simulation and verification system.
