Ultrasonic absorption spectroscopy can probe intermolecular interactions that inform research into chemical engineering and pharmaceutical manufacturing processes. The only commercial ultrasonic spectrometer costs over one hundred thousand dollars, putting

A QoE-Based Method for Quantifying and Comparing LTE Coverage

March 11, 2025
Author(s)
Wesley Garey, Yishen Sun, Richard Rouil
To determine the coverage of an LTE system, measurements such as the Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interfer-ence and Noise Ratio (SINR) are often used. However, RSRP and RSRQ are only
