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.

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 ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

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.
