winner2.wimparset

WINNER II model parameter configuration

Syntax

cfgWim = winner2.wimparset

Description

Download Required: To use winner2.wimparset, first download the WINNER II Channel Model for Communications Toolbox add-on.

cfgWim = winner2.wimparset returns a structure of WINNER II model parameters with their default values.

Examples

Create a WINNER II model parameter set

Use the winner2.wimparset function to create a WINNER II model parameter set.

cfgwim = winner2.wimparset;

Adjust default settings.

cfgwim.RandomSeed = 31; % Set the rng seed for repeatability
cfgwim.NumTimeSamples = 250;
cfgwim.CenterFrequency = 4e9;

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.
