name: NMSE
full_form: Normalized Mean Square Error
context: gain is unity (0dB). The accuracy of each model is specified as Normalised Mean Square Error (NMSE) between the modelled PA output and the measured/simulated PA output. The presented NMSE indicate very good agreement between the models and measurements. PA model for ~2 GHz commercially available GaAs with 40MHz signal bandwidth The first model is based on a commercially available GaAs PA designed for operation at 2.1GHz (band 1). The model has been derived from measurements with input and output data at a sample rate of 307.2 MHz and an input signal bandwidth of 40 MHz. The memoryless model has -31.5dB NMSE and is defined by: : [-0.618347-0.785905i
description: Normalized Mean Square Error (NMSE) is a parameter used to measure the accuracy of power amplifier (PA) models in telecommunications. It represents the difference between the modelled PA output and the measured/simulated PA output.
explanation: The text states that NMSE is a parameter used to measure the accuracy of PA models, classifying it as a parameter in the field of telecommunications.
