Thes e include atmospheric attenuation (rain fade\, gaseous absorption)\, Doppl er shifts due to platform mobility\, phase noise\, group delay distortion\ , non-linearities from high-power amplifiers\, and multipath effects in ce rtain scenarios (e.g.\, maritime or urban reflections for LEO systems).\n\ nThis talk presents how advanced RF channel emulators can be used to accur ately reproduce these real-world satellite impairments in a controlled lab oratory environment. The objective is to enable repeatable\, scalable\, an d high-fidelity testing of satellite links\, terminals\, and subsystems wi thout relying on costly and time-constrained over-the-air experiments. The presentation will cover: Physical-layer impairment modeling\, Implementat ion in channel emulators\, Test and validation workflows\, and Use cases\, including validation of adaptive coding and modulation (ACM)\, beam track ing algorithms\, and interference resilience in next-generation satellite systems (e.g.\, HTS and non-terrestrial networks for 5G/6G). Particular at tention will be given to the challenges associated with wideband and high- frequency systems (Ka-/Q-/V-band)\, where impairments are more pronounced and system margins are tighter.\n\nBy bridging the gap between theoretical channel models and practical system validation\, channel emulation emerge s as a critical tool for accelerating the development and certification of robust satellite communication technologies.\n\nCo-sponsored by: INRS/Sta racom\n\nAgenda: \n10 h-12 h : Talk & Discussion\n\n12h: Pizza\n\nRoom: 69 00\, Bldg: 6900\, 800 Rue De la Gauchetière Ouest\, Montréal\, Quebec\, Canada\, H5A 1K8\, Virtual: https://events.vtools.ieee.org/m/556737 LOCATION:Room: 6900\, Bldg: 6900\, 800 Rue De la Gauchetière Ouest\, Montr éal\, Quebec\, Canada\, H5A 1K8\, Virtual: https://events.vtools.ieee.org /m/556737 ORGANIZER:tarek.djerafi@inrs.ca SEQUENCE:25 SUMMARY:NTN in the Lab: Reproducing Real World Satellite Impairments with C hannel Emulators URL;VALUE=URI:https://events.vtools.ieee.org/m/556737 X-ALT-DESC:Description: <br /><p data-start="155" data-end="651"><span styl e="color: rgb(0\, 0\, 0)\;">Modern satellite communication systems operate in highly dynamic and non-ideal propagation environments\, where performa nce is strongly impacted by a combination of deterministic and stochastic impairments.
