MATLAB/Octave Implementation of WINNER II Propagation Model

This code repository contains a MATLAB/Octave software implementation of WINNER II path loss prediction method (Table 4-4). Note that only outdoor scenarios C1 (Suburban macro-cell), C2 (Urban macro-cell), and D1 (Rural macro-cell) are implemented in this version. The model supports LoS and NLoS propagation conditions as well as the LoS probabilities.

The following table describes the structure of the folder ./matlab/ containing the MATLAB/Octave implementation of the WINNER II model.

File/Folder	Description
tl_winner2.m	MATLAB/Octave implementation of WINNER II propagation model
winner2_RMa.m	Outdoor D1 scenario
winner2_SMa.m	Outdoor C1 scenario
winner2_UMa.m	Outdoor C2 scenario

Function call

L = tl_winner2(f, d, h1, h2, env, lostype, variations);

Required input arguments of function tl_winner2

Variable	Type	Units	Limits	Description
f	double	GHz	2 ≤ f≤ 6	Frequency
d	double	m	See Note	3D direct distance between Tx and Rx stations
h1	double	m	See Note	Antenna height of the first terminal
h2	double	m	See Note	Antenna height of the second terminal
env	string		'RURAL', 'SUBURBAN', 'URBAN'	Environment type
lostype	int			1 - LoS 2 - NLoS 3 - LoS Probability
variations	boolean			Set to true to compute variation in path loss (shadow fading)

Note

Maximum distance: 5 km (10 km for D1 LoS).
Minimum distance: 10 m (30 m for C1) for LoS and 50 m for NLoS.
Antenna heights must be positive (not smaller than 1 m for C2 LoS)

Output

Variable	Type	Units	Description
L	double	dB	Basic transmission loss
