%%%% DeepMIMO parameters set %%%%
% A detailed description of the parameters is available on DeepMIMO.net

%Ray-tracing scenario
params.scenario = 'O1_60';          % The adopted ray tracing scenario [check the available scenarios at https://deepmimo.net/scenarios/]

%Dynamic Scenario Scenes [only for dynamic (multiple-scene) scenarios]
params.scene_first = 1;
params.scene_last = 1;

% Active base stations
params.active_BS = [1];             % Includes the numbers of the active BSs (values from 1-18 for 'O1')(check the scenario description at https://deepmimo.net/scenarios/ for the BS numbers) 

% Active users
params.active_user_first = 1;       % The first row of the considered user section (check the scenario description for the user row map)
params.active_user_last = 44;       % The last row of the considered user section (check the scenario description for the user row map)

% Subsampling of active users
%--> Setting both subsampling parameters to 1 activate all the users indicated previously
params.row_subsampling = 1;         % Randomly select round(row_subsampling*(active_user_last-params.active_user_first)) rows
params.user_subsampling = 1;        % Randomly select round(user_subsampling*number_of_users_in_row) users in each row

% Antenna array dimensions
params.num_ant_BS = [8, 1];      % Horizontal - Vertical
params.num_ant_UE = [1, 1];      % Horizontal - Vertical

params.FoV_ant_BS = [180, 180]; % Degrees in horizontal-vertical Max- 360 180
params.FoV_ant_UE = [360, 180]; % Degrees in horizontal-vertical

% Antenna array orientations
params.array_rotation_BS = [0, -45, 0];         
params.array_rotation_UE = [0, 0, 0];    
% 3D rotation angles in degrees around the x,y,z axes respectively
% The rotations around x,y,z are also called as slant, downtilt, and bearing angles (of an antenna towards +x)
% The origin of these rotations is the position of the first BS antenna element
% The rotation sequence applied: (a) rotate around z-axis, then (b) rotate around y-axis, then (c) rotate around x-axis. 
% To define different orientations for the active BSs, add multiple rows..
% Example: For two active BSs with different array orientations, you can define
% params.array_rotation_BS = [[10, 30, 45]; [0, 30, 0]];

% User antenna orientation settings
% For uniform random selection in
% [x_min, x_max], [y_min, y_max], [z_min, z_max]
% set [[x_min, x_max]; [y_min, y_max]; [z_min, z_max]]
% params.array_rotation_UE = [[0, 30]; [30, 60]; [60, 90]]; 

% Antenna array spacing
params.ant_spacing_BS = .5;           % ratio of the wavelength; for half wavelength enter .5
params.ant_spacing_UE = .5;           % ratio of the wavelength; for half wavelength enter .5


% Antenna element radiation pattern
params.radiation_pattern = 0;         % 0: Isotropic and 
                                      % 1: Half-wave dipole
                 

% System parameters
params.bandwidth = 0.05;              % The bandwidth in GHz

                                      % 1 Apply RX low-pass filter (ideal: Sinc in the time domain)

% Channel parameters # Activate OFDM
params.generate_OFDM_channels = 1;    % 1: activate frequency domain (FD) channel generation for OFDM systems
                                      % 0: activate instead time domain (TD) channel impulse response generation for non-OFDM systems
params.num_paths = 25;                 % Maximum number of paths to be considered (a value between 1 and 25), e.g., choose 1 if you are only interested in the strongest path

% OFDM parameters
params.num_OFDM = 512;                % Number of OFDM subcarriers
params.OFDM_sampling = [1];           % The constructed channels will be calculated only at the sampled subcarriers (to reduce the size of the dataset)

params.enable_Doppler = 0;            % Enable Doppler shift (if available in the scenario)
params.dual_polar = 0;                % Enable cross dual-polar antenna (if available in the scenario)
