A method to achieve clear-sky data-volume download in satellite links affected by tropospheric attenuation
For data downloading from satellites, the traditional approach of considering the complementary probability distribution, PAtrop of the total tropospheric attenuation AtropdB, at a frequency, polarization, and elevation angle, may be too pessimistic, ...
Satellite constellation design for telecommunication in Antarctica
This paper addresses the problem of designing a small satellite constellation suitable for communications in Antarctica. This study has been motivated by the increasing international interests in having permanent bases in Antarctica to perform ...
A congestion control middleware layer with dynamic bandwidth management for satellite communications
Historically, satellites have been set aside for what regards Internet connectivity; however, the interest in their usage to provide Internet connectivity is now rising again. Because of the growing demand for Internet services around the world, ...
A new design approach for dual-band patch antenna serving Ku/K band satellite communications
A printed planar antenna with simple and intelligent geometrical structure has been proposed for Ku/K band satellite communication systems. The radiating patch of the antenna is formed by cutting rectangular slots and extending the radiating element to ...
Code design for adaptive coding and modulation indicator in broadcast systems
In this paper, we address the coding problem for adaptive coding and modulator indicators in communication systems where users are divided into several classes according to their channel quality. Two novel methods are described to construct codebooks ...
A channel state-driven ACM algorithm for mobile satellite communications
The last decade has been characterized by an increasing demand of higher throughput and more reliable communication links for supporting multimedia applications. To this aim, the focus has been toward both broadband and broadcast solutions providing ...
Space communications with variable elevation angle faded by rain: Radio links to the Sun-Earth first Lagrangian point L1
How rain attenuation affects space links with variable elevation angles is not yet fully researched. The aim of this paper is to investigate this topic by simulating rain attenuation at Ka Band, in slant paths with variable elevation angles, with the ...
Efficient soft demodulation schemes for the DVB-S2X system
In this paper, we propose efficient soft demodulation methods for the 64, 128, and 256 amplitude and phase shift keying schemes defined in the digital video broadcasting via satellite second-generation system. We first derive hard decision threshold HDT ...
