Infants and Mobiles: Developing an Understanding of Cause and Effect
Developmental Science, Volume 29, Issue 4, July 2026.ABSTRACT In the mobile conjugate reinforcement paradigm, an infant's leg is connected to a mobile via a string, allowing the infant to move the mobile via moving their leg. Over a few minutes, infants exhibit an increase in the frequency of movement of the connected leg.

Parametric Channel Estimation for Massive MIMO [PDF]
2018 IEEE Statistical Signal Processing Workshop (SSP), 2018 Channel state information is crucial to achieving the capacity of multi-antenna (MIMO) wireless communication systems. It requires estimating the channel matrix. This estimation task is studied, considering a sparse channel model particularly suited to millimeter wave propagation, as well as a general measurement model taking into account hybrid ...

A Joint Channel Modeling, Parameter Estimation and Geometry‐Based Indoor Localization for 5G Systems
Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 6, June 2026.We propose an end‐to‐end method to accurately localize mobile stations in indoor scenarios, such as those found in Industry 4.0. To this end, we jointly perform wireless channel modeling considering mmWave and MIMO technologies, parameter estimation in 3D, and simple and fine‐grained geometry‐based localization.

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, Volume 20, Issue 11, 5 June 2026.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Spatial Multiplexing for MIMO/Massive MIMO
, 2023 In this chapter, we will discuss how to achieve spatial multiplexing in multiple-input multiple-output (MIMO) communications through precoding design, for both traditional small-scale MIMO systems and massive MIMO systems. The mathematical description for MIMO communications will first be introduced, based on which we discuss both block-level precoding

Jamming resistant receivers for massive MIMO [PDF]
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017 We design jamming resistant receivers to enhance the robustness of a massive MIMO uplink channel against jamming. In the pilot phase, we estimate not only the desired channel, but also the jamming channel by exploiting purposely unused pilot sequences.

Symbol‐Level GRAND‐Assisted Detection for Polar‐Coded Spatial Modulation in MIMO Systems
International Journal of Communication Systems, Volume 39, Issue 7, 10 May 2026.This research presents an integrated polar‐coded spatial modulation (PCSM) transceiver scheme for MIMO transmission over Rayleigh fading channels. The proposed architecture employs linear spatial signal processing for antenna and symbol estimation, followed by symbol‐level guessing random additive noise decoding (symbol‐level GRAND)–assisted detection ...
