High Altitude Platform Station (HAPS) system is a new, promising means of providing Third Generation (3G) mobile services. While HAPS can be affected by stratospheric winds. In this paper, a novel HAPS-CDMA displacement model is presented. And the impacts of platform displacements in the horizontal and vertical direction are examined. From numerical(More)
Non-static transmission time interval (TTI) strategy is investigated in this paper, in order to improve the available potential performance of the enhanced uplink dedicated channel in universal telecommunication radio access low chip rate time division duplex system (UTRA LCR TDD). This strategy introduces a joint support of two kinds of TTI, 20ms and 5ms(More)
