Output Arguments
cfgWim
— Configuration layout
structure
Configuration model, returned as a structure containing these fields.
NumTimeSamples
— Number of time samples
100
(default) | scalar
Number of time samples, specified as a scalar.
FixedPdpUsed
— Use predefined path delays and powers for specific scenarios
'no'
(default) | 'yes'
Use predefined path delays and powers for specific scenarios,
specified as 'no'
or 'yes'
.
FixedAnglesUsed
— Use predefined path angles of departure (AoDs) and angles of arrival (AoAs) for specific scenarios
'no'
(default) | 'yes'
Use predefined path angles of departure (AoDs) and angles of
arrival (AoAs) for specific scenarios, specified as 'yes'
or 'no'
.
IntraClusterDsUsed
— Divide each of the two strongest clusters into three subclusters per link
'yes'
(default) | 'no'
Divide each of the two strongest clusters into three subclusters
per link, specified as 'yes'
or 'no'
.
PolarisedArrays
— Use dual-polarized arrays
'yes'
(default) | 'no'
Use dual-polarized arrays, specified as 'yes'
or 'no'
.
UseManualPropCondition
— Use manually defined propagation conditions
'yes'
(default) | 'no'
Use manually defined propagation conditions, specified as 'yes'
or 'no'
.
Set to 'yes'
to enforce the use of manually defined
propagation conditions (LOS/NLOS) in the PropagConditionVector
structure
field returned by winner2.layoutparset
.
Set to 'no'
to draw propagation conditions from
pre-defined LOS probabilities.
CenterFrequency
— Carrier frequency
5.25e9
(default) | scalar
Carrier frequency in Hz, specified as a scalar.
UniformTimeSampling
— Enforce uniform time sampling
'no'
(default) | 'yes'
Enforce all links to be sampled at the same time instants, specified
as 'no'
or 'yes'
.
SampleDensity
— Number of time samples per half wavelength
2e6
(default) | scalar
Number of time samples per half wavelength, specified as a scalar.
DelaySamplingInterval
— Sampling interval
5e-9
(default) | scalar
Sampling interval, specified as an scalar indicating the input
signal sample time in seconds. DelaySamplingInterval
defines
the sampling grid to which the path delays are rounded. A value of 0
seconds
indicates no rounding on path delays.
ShadowingModelUsed
— Use shadow fading
'no'
(default) | 'yes'
Use shadow fading, specified as 'no'
or 'yes'
.
PathLossModelUsed
— Use path loss model
'no'
(default) | 'yes'
Use path loss model, specified as 'no'
or 'yes'
.
PathLossModel
— Path loss model
'pathloss'
(default) | character vector
Path loss model, specified as a character vector representing
a valid function name. PathLossModel
applies
only when PathLossModelUsed
is set to 'yes'
.
PathLossOption
— Wall material
'CR_light'
(default) | 'CR_heavy'
| 'RR_light'
| 'RR_heavy'
Wall material, specified as 'CR_light'
, 'CR_heavy'
, 'RR_light'
,
or 'RR_heavy'
, indicating the wall material for
the A1 scenario NLOS path loss calculation. PathLossOption
applies
only when PathLossModelUsed
is set to 'yes'
.
RandomSeed
— Seed for random number generators
[]
(default) | scalar
Seed for random number generators, specified as a scalar or
empty brackets. Empty brackets, []
, indicate that
the global random stream is used.
