AWGN
AWGN, also referred to as
oc
N
, in 3GPP specifications, is defined as the power spectral density of a white
noise source (average power per resource element (RE) normalized to the subcarrier spacing), simulating
interference from cells, as measured at the UE antenna connector.
Note that the AWGN is determined by using a signal to noise ratio relative to the cell power.
You can change the cell power level without changing AWGN settings, enabling
you to maintain a constant signal to noise ratio, when required.
This menu key enables you to access the following functions:

Dependencies and/or Couplings AWGN is determined by using a signal to noise ratio relative to the cell
power and is therefore dependent upon the cell power.
