Compensation of Transmitter IQ Imbalance in Multi-User Hybrid Beamforming Systems

open access: yesIEEE Access, 2021
In this paper, we consider the uplink (UL) communication of a massive multi-user (MU) multiple-input multiple-output (MIMO) hybrid beamforming system (HBFS) in which the transmitting user-equipments are affected by IQ imbalance (IQI).

Observations of Ionospheric Disturbances Produced by a Powerful Very-Low-Frequency Radio Signal in the Magnetic Conjugated Region Respect the Transmitter

open access: yesRemote Sensing, 2023
We investigate four observational cases over NWC magnetically conjugate region by DEMETER spacecraft and CSES satellite. The cases of DEMETER on 23 February 2008 and CSES on 22 March 2020 show the evident ionospheric heating effects, in which the ...

Energetic contributions to channel gating of residues in the muscle nicotinic receptor β1 subunit. [PDF]

open access: yesPLoS ONE, 2013
In the pentameric ligand-gated ion channel family, transmitter binds in the extracellular domain and conformational changes result in channel opening in the transmembrane domain.

An evaluation of transmitter effects on adult and juvenile Common Terns using leg-loop harness attachments

open access: yesJournal of Field Ornithology, 2022
Marking birds with transmitters allows for the collection of data that are critical for fully understanding avian life history, but researchers must also be confident that performing such studies is as safe as possible for transmittered individuals ...
