• Jeffery A. Wepman et al., “Measured Out-of-Band Emissions in the 36–37 GHz Band from an n260 (37–40 GHz) Millimeter-Wave 5G Base Station,” Technical Report NTIA TR-26-582, June 2026

  Out-of-band emissions (OOBE) measurements in the 36–37 GHz band were performed on a commercially available outdoor 5G millimeter-wave (mmWave) gNodeB operating in the n260 band (37–40 GHz). The 5G mmWave gNodeB is part of the Institute for Telecommu...

• Jaden Pieper and Stephen D. Voran, “Analysis of Multiple Noisy Measurements and their Resamplings via Expected Values of Correlation and Mean-Squared-Error,” Technical Memorandum NTIA TM-26-581, March 2026

  This memorandum provides mathematical relationships for agreement between true measurand values, means of multiple imperfect measurements, and resampled measurement means. Agreement is quantified here in terms of Pearson correlation coefficient (PCC...

• Jaden Pieper and Stephen D. Voran, “Unseen but not Unknown: Using Dataset Concealment to Robustly Evaluate Speech Quality Estimation Models,” Conference Paper, February 2026

  We introduce Dataset Concealment (DSC), a rigorous new procedure for evaluating and interpreting objective speech quality estimation models. DSC quantifies and decomposes the performance gap between research results and real-world application requir...

• Mustafa Harun Yılmaz, “Adjacent Channel Interference Analysis From U-NII-4 and U-NII-5 Devices Into 5G NR V2X Devices,” Journal Article, February 2026

  The Federal Communications Commission in the U.S. assigned 30 MHz from the 5895–5925 MHz band for vehicular communication. Adjacent bands, i.e., from 5850–5895 MHz and 5925–6425 MHz, were designated for unlicensed devices. In this study, the effect ...
