Optimization-Based Wi-Fi Radio Map Construction for Indoor Positioning Using Only Smart Phones [PDF]
Sensors, 2018 Fingerprinting-based Wi-Fi indoor positioning has great potential for positioning in GPS-denied areas. However, establishing a fingerprinting map (also called a radio map) prior to positioning (site survey) is normally a labor-intensive task.

On the Construction of Radio Environment Maps for Cognitive Radio Networks [PDF]
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013 The Radio Environment Map (REM) provides an effective approach to Dynamic Spectrum Access (DSA) in Cognitive Radio Networks (CRNs). Previous results on REM construction show that there exists a tradeoff between the number of measurements (sensors) and ...

Space-Frequency-Interpolated Radio Map [PDF]
IEEE Transactions on Vehicular Technology, 2021 This paper presents a novel method for radio map construction that simultaneously interpolates the received signal power values over space and frequency domains. Radio maps can be used to improve spectrum management and for localization systems, which are related to wireless systems in general such as cellular systems, Internet of Things (IoT) networks,

Symposium - International Astronomical Union, 1988 The mapping discussed in this paper is based on observations obtained from the 21–cm emission line of neutral atomic hydrogen. We will give an overview of the existing large surveys and present a homogeneous datacube that contains the most important surveys.

Optical–Radio Mapping: the Kinetic Efficiency of Radio‐Loud AGNs [PDF]
The Astrophysical Journal, 2008 We constrain the mean kinetic efficiency of radio-loud active galactic nuclei by using an optically selected sample for which both the optical and the radio luminosity functions (LFs) have been determined; the former traces the bolometric luminosity L, while the latter traces the kinetic power L_k, empirically correlated to the radio emission.
