full_form: Total Radiated Sensitivity (also: Total Isotropic Sensitivity)
context: This measurement checks that the resulting Power Delay Profile (PDP) is like defined in the channel model. Method of measurement: Step the emulation and store traces from VNA. I.e. run the emulation to CIR number 1, pause, measure VNA trace, run the emulation to CIR number 10, pause, measure VNA trace. Continue until 1000 VNA traces are measured. VNA settings: Table 8.3.2.1-1: VNA settings for PDP Channel model specification: Table 8.3.2.1-2: Channel model specification for PDP Method of measurement result analysis: Measured VNA traces (frequency responses H(t,f)) are saved into a hard drive. The data is read into, e.g., Matlab. The analysis is performed by taking the Fourier transform of each FR. The resulting impulse responses h(t,tau) are averaged in power over time: Finally the resulting PDP is shifted in delay, such that the first tap is on delay zero. The reference PDP plots from Table 8.2-1 and Table 8.2-2 are shown in Figure 8.3.2.1-1. OTA antenna configuration: For e.g. 1 full
description: Total Radiated Sensitivity (TRS) is a measure of the total radiated power received by a device, used to evaluate its Over-The-Air (OTA) performance in various operating modes and positions. It provides a benchmark for assessing the device's ability to transmit and receive signals effectively.
explanation: The context from 3GPP TS 25.144 highlights TRS as a key metric for evaluating OTA performance, with recommended values provided in tables for different scenarios (FDD, GSM, UTRA LCR TDD). This indicates that TRS is used to measure and compare the radiated sensitivity of devices under various conditions.
