Propagation Impairment Countermeasures in Mobile Stratospheric Operating Environment

Abstract

The efficiency of wireless communication systems largely depends on proper understanding of propagation impairments and the design of suitable countermeasures, taking into account physical causes and time-scales of propagation phenomena. The primary focus of this paper is the link between High Altitude Platform (HAP) and a collective mobile terminal onboard high speed train. The paper characterizes the temporal behavior of the propagation channel on this link by means of first-and second-order statistics, presents a QoS framework based on IP architecture, and discusses potential propagation impairment countermeasures from the perspective of their usage in the provision of different services.
