Diversity technique evaluation for LTE high mobility user based on high altitude platform

Abstract

HAPS (High Altitude Platform Station) is an alternative technology of communication system that utilizes terrestrial and satellite systems. HAPS technology is located in the stratosphere layer with the height of 17-22 km above the earth’s surface. HAPS has some advantages, which are wide range area, communication ability on line of sight (LOS), and low propagation delay. In this paper we present the comparison between single HAPS system and two HAPS diversity technique. From simulation result, it is evident that using two HAPS as a diversity technique gives better performance than the single HAPS system, it is shown by how the two HAPS diversity technique requires less SNR than the single HAPS system, typically 3 dB less of SNR.
