The stationarity of Land Mobile Satellite (LMS) channels is investigated. It is shown that the evaluation of the time-varying channel stationarity is essential before data processing for parameter extraction. This is illustrated by several examples using real-world datasets.
Research on mobile satellite and high-altitude platform (HAP) systems (MSHSs) has recently proliferated because of the allocation of additional spectrum, the intense standardization efforts from different international institutes, the detailed studies pursued by the European [European Space Agency (ESA)], French (CNES), and Japanese (JAXA) space agencies, and the commercial impact of some of the corresponding...
A multipath model for the aeronautical channel, which was derived from a channel measurement campaign, has been implemented into hardware simulators. The way of implementation is described in detail and simulation results obtained with a GNSS receiver and showing the impact of multipath are presented.
The further development of multipath mitigation methods for Global Navigation Satellite Systems (GNSS) depends on the knowledge of the wave propagation circumstances present in various scenarios. The modeling of the multipath propagation properties for land-mobile users play a vital role in modern GNSS receiver algorithm development. This paper proposes a model for the simulation of a vehicle traveling...
