Collection Methods for High-SNR I/Q Recordings of FDD LTE User Equipment Emissions



Keith Forsyth, Aric Sanders, Dan Kuester, Adam Wunderlich


This report documents collection methods for high signal-to-noise ratio (SNR) in-phase and quadrature (I/Q) radio frequency (RF) recordings of long-term evolution (LTE) uplink emissions from a commercial-off-the-shelf (COTS) handset in a fully conducted environment. A base station emulator was used to configure the handset to statically transmit over various LTE physical resource block configuration for 1.4 MHz, 3 MHz, 5 MHz, and 10 MHz uplink channels centered at 1770 MHz in LTE Band 66, which is a frequency-division duplex (FDD) band. The aim of this effort was to acquire a dataset that could be used to aid the development of computational models for emissions from real-world communication hardware.
