Sparse Channel Estimation for Massive MIMO-OFDM Systems Over Time-Varying Channels

IEEE Access, 2018
For downlink orthogonal frequency division multiplexing-based massive multiple-input-multiple-output transmission over the time-varying channel, channel estimation is very challenging due to numerous channel coefficients to be estimated.

TraceMyFish D2.4 Pilot Design and Piloting plan (v2.0)

, 2023
The objective of WP2 entitled as “Tracking hazards and potential measures” is to define and outline the corresponding settings of all three pilots of TMF project, so as to enable tracing the potential hazards across the Bluebio value chain affecting food quality and safety along three crucial value chains in Europe, and more precisely: 1) the Atlantic ...

A Bayesian approach to pilot-pivotal trials for bioequivalence assessment

BMC Medical Research Methodology, 2023
Background To demonstrate bioequivalence between two drug formulations, a pilot trial is often conducted prior to a pivotal trial to assess feasibility and gain preliminary information about the treatment effect. Due to the limited sample size, it is not

Pilot-Efficient Channel Estimation for RIS-Aided Wireless Communication Systems: A Systematization

IEEE Open Journal of the Communications Society
Passive reconfigurable intelligent surfaces (RIS) can reshape the propagation environment with negligible radio-frequency power, yet they introduce a dominant channel-acquisition bottleneck, because the cascaded channel to be learned is high-dimensional ...

Conditioning-Centric Design of RIS-Assisted Uplink Channel Estimation Under Heterogeneous Propagation

IEEE Open Journal of the Communications Society
Reconfigurable intelligent surfaces (RIS) allow programmable wireless propagation but add intrinsic problems in the estimation of the uplink channel because of high-dimensional cascaded channels, limited pilot budgets, heterogeneous propagation, and ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Pilot Implementation: Testing Human-Work Interaction Designs

, 2021
Pilot implementations are field tests of properly engineered, yet unfinished, systems. In contrast to lab tests, the users in a pilot implementation use the system for performing real work. In contrast to full-scale implementations, the objective of a pilot implementation is to learn.

Improved Early Referral in Long‐Term Survivor Care With Institutional Standardized Practice Among Childhood Leukemia Survivors#

Pediatric Blood &Cancer, EarlyView.
ABSTRACT In 2018, the Texas Children's Cancer and Hematology Center Leukemia Program implemented a practice standard to support the transition from treatment to survivorship that includes shared, alternating care between leukemia and survivorship clinicians and a reminder to refer survivors to the long‐term survivor clinic (LTSC) 2 years after ...
