WINNER II model parameter configuration


Download Required: To use this function, first download the WINNER II Channel Model for Communications Toolbox™ from the Add-On Explorer. For more information on downloading add-ons, see Get and Manage Add-Ons (MATLAB).


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


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

collapse all

Configuration model, returned as a structure containing these fields.

Number of time samples, specified as a scalar.

Use predefined path delays and powers for specific scenarios, specified as 'no' or 'yes'.

Use predefined path angles of departure (AoDs) and angles of arrival (AoAs) for specific scenarios, specified as 'yes' or 'no'.

Divide each of the two strongest clusters into three subclusters per link, specified as 'yes' or 'no'.

Use dual-polarized arrays, specified as 'yes' or '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.

Carrier frequency in Hz, specified as a scalar.

Enforce all links to be sampled at the same time instants, specified as 'no' or 'yes'.

Number of time samples per half wavelength, specified as a 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.

Use shadow fading, specified as 'no' or 'yes'.

Use path loss model, specified as 'no' or 'yes'.

Path loss model, specified as a character vector representing a valid function name. PathLossModel applies only when PathLossModelUsed is set to 'yes'.

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'.

Seed for random number generators, specified as a scalar or empty brackets. Empty brackets, [], indicate that the global random stream is used.
