The Importance of Pilot Studies [PDF]

open access: yes, 2001
The term 'pilot studies' refers to mini versions of a full-scale study (also called 'feasibility' studies), as well as the specific pre-testing of a particular research instrument such as a questionnaire or interview schedule.

Non-Orthogonal Pilot Designs for Joint Channel Estimation and Collision Detection in Grant-Free Access Systems

open access: yesIEEE Access, 2018
In this paper, we consider a densely deployed phantom cell system providing a low latency network for massive connectivity. Non-orthogonal pilot designs serve as a promising solution to support a large number of users, but fast collision detection at the

Leveraging Waveform Structure to Develop a Power Scalable AoA Estimation

open access: yesIEEE Open Journal of the Communications Society, 2021
In a mmWave mobile device, power consumption resulting from the high sampling rate is a primary concern for angle of arrival (AoA) estimation solutions. In this paper, we provide a power scalable solution for AoA estimation with structured waveforms in a

What is a pilot or feasibility study? : a review of current practice and editorial policy [PDF]

open access: yes, 2010
Background In 2004, a review of pilot studies published in seven major medical journals during 2000-01 recommended that the statistical analysis of such studies should be either mainly descriptive or focus on sample size estimation, while results from ...

BLEXVFR: Designing a Mobile Assistant for Pilots [PDF]

open access: yesAdjunct Publication of the 23rd International Conference on Mobile Human-Computer Interaction, 2021
Piloting an aircraft is a difficult task that requires high-level cognitive abilities. Few studies have investigated the use of cognitive assistants to support pilots. This study is a first step toward an in-flight assistant for light aircraft pilots.

Compressive Sensing-Based Secure Uplink Grant-Free Systems

open access: yesFrontiers in Signal Processing, 2022
Compressive sensing (CS) has been extensively employed in uplink grant-free communications, where data generated from different active users are transmitted to a base station (BS) without following the strict access grant process. Nevertheless, the state-
