Profile
Selects one of the propagation condition defined in the table 6.4.1-1 of 3GPP2
C.S0032.
Different fading propagation profiles support various vehicle speeds, numbers of paths,
path power and delay.
Remote command:
Restart Event
In "Auto" mode, fading automatically starts with the forward signal. In "Manual" mode, it
is started and restarted manually.
Remote command:
Start Seed
Sets the start seed for the pseudo-random fading algorithm. This enables reproducible
fading conditions.
Remote command:
Insertion Loss
In "Normal" mode, the insertion loss (i.e. the required attenuation at fader input) is cal-
culated based on the currently selected
. In "Manual" mode it can be adjusted by
the user.
A lower insertion loss allows for a higher forward link power but may result in clipping.
Remote command:
Clipping Counter
Displays the percentage of clipped samples.
This information is useful for insertion loss mode "Manual". It allows you to find the low-
est insertion loss value for which no clipping occurs.
Remote command:
Doppler Frequency
Displays the maximum Doppler frequency resulting from the selected fading profile.
2.4.6.2
Forward Link Settings
This branch displays noise power values, calculated from the forward link power and
the fading module AWGN settings.
