Ka‐band HTS channel uplink SNIR probability model

Abstract

SUMMARYI present a novel analytical study of the signal-to-noise-plus-interference ratio (SNIR) for Ka-band high throughput satellite uplink channels. The Ka-band high throughput satellite systems employ frequency and polarization (color) reuse among the spot beams to achieve throughput increase many times the throughput of the system without reuse. However, color reuse also produces substantial co-color interference and adding to it, tropospheric precipitation attenuation rises sharply in Ka-band. The co-color interference and precipitation induced fading vary randomly; they degrade the system performances. To assess the impact, I develop the uplink channel SNIR probability model in this study. Compared with the known studies of the same topic, this study takes the theoretic approach and is applicable to the urban users in particular. The model is feasible to implement and can provide accurate assessment of the channel SNIR performances statistically in theory for a wide array of system operational scenarios. The SNIR probability model is applied to a model spot beam system of 101 user beams to obtain and compare sample channel performances, which can be used for making system design choices at the early stage of a satellite project.

Band K Satellite Receiver Signal and Radio Locator

“…The antenna position control system is based on a microprocessor, see Figure 7. To measure the position of the antenna at the azimuth, an impulse transducer was used [Drieß, Evers and Brückner 2012;Liping 2017]. The position of the antenna at azimuth is converted into an appropriate number of pulses, which after conversion to the value of the angle is displayed on the indicator.…”

On the Impact of Satellite Communications Over Mobile Networks: An Experimental Analysis

“…Several works exist in the literature that study satellite integration with cellular networks [7], [8], [9], [10], [11], [12], [13], [14]. Different satellite-5G integration use cases as well as the latest initiatives and challenges in future 5G terrestrial and satellite integration are summarized in [7].…”

“…Additionally, various works investigate satellite communication in Ka band [9], [10], [24], [25]. The authors in [9] focus on extending the LTE broadband service using a megaconstellation of LEO satellites that are deployed in Ka-band.…”

“…The authors in [9] focus on extending the LTE broadband service using a megaconstellation of LEO satellites that are deployed in Ka-band. An Uplink (UL) signal-to-interference-plus-noise ratio (SINR) probabilistic model for Ka band in HTSs is studied in [10]. The authors in [24] focus on beam tracking methodology in Ka-band for UAV-satellite communication systems.…”
