W-cdma via High Altitude Platform Station System
In similar with terrestrial and satellite wireless networks, a new alternative based on platforms located in the stratosphere has recently introduced, known as High Altitude Platforms (HAPS). HAPS are either airships or aircraft positioned between 17 and 22.5 km above the earth surface. It has capability to deliver a wide spectrum of applications to both mobile and fixed users over a broad cove...
متن کاملSofter Handover Schemes for High Altitude Platform Station (HAPS) UMTs
An important property of high altitude platform station (HAPS) Universal Mobile Telecommunications Systems (UMTS) is that unlike terrestrial tower based systems. interference is dependent on the antenna characteristics of HAPS rather than the terrain features (i.e., shadowing) in the service area. In this paper. we exploit this unique HAPS property to propose simple and effective adaptive softe...
متن کاملHigh Altitude Platform Station Network and Channel Modeling Performance Analysis
High altitude platform station (HAPS) is a wireless repeater in the air. It can play a dominant role in observations, remote sensing and communication. The structure and composition of formation of HAPS are studied in this paper. The performance of the wireless communication link are researched. The simulation results shows that the power of receiver is proportional to the received power and th...

متن کاملA Novel Beamforming Technique for Highways Coverage Using High-Altitude Platforms
This paper proposes a novel beamforming technique to form an arbitrary-shaped cell for the high-altitude platforms (HAPs) mobile communications. The new technique is based on pattern summation of individual low-sidelobe, narrow beams which constitute the desired cell pattern weighted by an amplitude correcting function. The new cell pattern can be adapted to cover the main highways forming worm...
