During 1993–1994, the T1A1 subcommittee of the American National Standards Association (ANSI) accredited Alliance for Telecommunications Industry Solutions (ATIS) conducted an objective video quality metric validation test focused on video teleconfe...
This paper introduces ITU-T Recommendation P.913, a new subjective video quality testing standard approved in January 2014. This Recommendation focuses on the evaluation of flat screens, laptops, and mobile devices. P.913 emphasizes flexibility of e...
In response to proposals to introduce new Long Term Evolution (LTE) radio systems into the 3550–3650 MHz (called 3.5 GHz) portion of radio spectrum in the United States, a joint team of National Telecommunications and Information Administration (NTIA...
The 13th Annual International Symposium on Advanced Radio Technologies, held in Boulder, Colorado, July 24–26, 2012, presented the second conference focused on Developing Forward Thinking Rules and Processes to Fully Exploit Spectrum Resources. Follo...
We propose a model for rating behavior based on subject bias and subject error. Evidence for subject bias can be found in freely available subjective experiments. When subject bias is removed from ratings, the sensitivity of statistical comparisons b...
In response to proposals to introduce new radio systems into 3.5 GHz radio spectrum in the United States, the authors have performed measurements and analysis on effects of interference, from a variety of radar waveforms, to the performance of a prot...
In response to proposals to introduce new Long Term Evolution (LTE) microcell Citizens Broadband Service (CBS) radio systems into 3550–3650 MHz (3.5 GHz) radio spectrum in the United States, the authors have performed measurements and analysis on eff...
This report provides full technical details for the video quality subjective test AGH/NTIA. Analyses of this dataset appear in separate publications. The purpose of this document is to provide design details that are beyond the scope of a conference...
The measurement of a radar chirp waveform is critical to assessing its spectral compliance. The Fourier transform for a linear frequency-modulated chirp is a sequence of frequency-domain impulse functions. Because a spectrum analyzer measures the wa...
In response to the Presidential Memorandum on Wireless Innovation and the recommendation of the Presidential Council of Advisors on Science and Technology (PCAST), the federal government has begun the process of organizing a National Advanced Spectru...
NTIA is responsible for managing the Federal Government’s use of the radio spectrum. In discharging this responsibility, NTIA uses the Radio Spectrum Measurement System to collect spectrum occupancy data for radio frequency assessments. This report s...
The VQEG eletter publishes up-to-date technical advances on video quality related topics. The VQEG eLetter also makes available limited distribution publications that contain valuable technical information, such as out-of-print ATIS contributions. T...
This is the third edition of a handbook intended to help Institute for Telecommunication Sciences (ITS) staff produce reports and papers in accordance with ITS, National Telecommunications and Information Administration, Department of Commerce, and F...

An immersive subjective test method is proposed in which subjects view each source stimulus only once. In order to encourage a subject’s engagement with test content, longer stimuli are used. Distractor questions are used in addition to the tradition...
The Web-Enabled Subjective Test software allows researchers to conduct subjective tests on multiple devices with aggregated data collection and reporting. The system leverages modern web technologies and infrastructure to deliver test stimuli to typi...
This report presents spectrum occupancy data of the 3550–3650 megahertz (MHz) maritime radar band measured in June 2012 near San Diego. In this band, the military operates SPN-43 air marshaling radar systems with well-defined signal characteristics. ...

NTIA is responsible for managing the Federal Government’s use of the radio spectrum. In discharging this responsibility, NTIA uses the Radio Spectrum Measurement Sciences system to collect spectrum occupancy data for radio frequency assessments. Thi...
We present an objective estimator of speech intelligibility that follows the paradigm of the Modified Rhyme Test (MRT). For each input, the estimator uses temporal correlations within articulation index bands to select one of six possible words from ...
