A new means for providing wireless communication has been currently proposed. It is based on aerial vehicle known as
High Altitude Platform or Stratospheric Platforms (SPF). The SPF will be operated at an altitude of 17-22 km above the
ground. Therefore, the channel condition may be different compared with those of the conventional terrestrial or
satellite wireless channel. In this paper, the channel propagation characteristic of such a system is firstly investigated by
means of ray tracing algorithm. We ...

We propose an analysis of reverse link CDMA multispot beam stratospheric platforms (SPF) in this paper. The SPF is
currently proposed as a novel wireless technology for the development of the next generation fixed and mobile
communications. The geometry of this technology is different from that of the terrestrial but rather similar to the
satellite based cellular system. However, evaluation on the CDMA system capacity of this technology has not been
much reported. This paper addresses all possible multiple ...
