%WIM_CORE Channel coefficient computation for a geometric channel model
%   [H DELTA_T FINAL_PHASES FINAL_PHASES_LOS]=WIM_CORE(WIMPAR,LINKPAR,ANTPAR,BULKPAR,BSGAIN,BSGAIN_LOS,MSGAIN,MSGAIN_LOS,OFFSET_TIME, BSGAINISSCALAR, MSGAINISSCALAR)
%   This is the wim_core aka the big for loop. It implements the formula in
%   [2, Eq. 3.26-28].
%
%   Outputs:
%
%   H               - [UxSxNxTxK] array of channel coefficients
%   DELTA_T         - time sampling intervals (in seconds) for all links
%   FINAL_PHASES    - final phases of all subpaths in degrees over (-180,180)
%   FINAL_PHASES_LOS- final phases for LOS paths in degrees over (-180,180)
%   
%   Inputs:
%
%   WIMPAR          - input struct, see WIMPARSET
%   LINKPAR         - input struct, see LINKPARSET
%   ANTPAR          - input struct, see ANTPARSET
%   BULKPAR         - input BULKPAR, see GENERATE_BULK_PAR
%   BSGAIN          - [KxSxNxM] array of interpolated antenna field
%                     patterns (complex)
%   BSGAIN_LOS      - [KxS] array of interpolated antenna field patterns
%                     (complex) for LOS paths. Only used with the LOS
%                     option; it is set to scalar otherwise.
%   MSGAIN          - [KxUxNxM] array of interpolated antenna field
%                     patterns (complex)
%   MSGAIN_LOS      - [KxU] array of interpolated antenna field patterns
%                     (complex) for LOS paths. Only used with the LOS
%                     option; it is set to scalar otherwise.
%   OFFSET_TIME     - time offset added to the initial phase (set to zero by default)
%   BSGAINISSCALAR  - this is 1 if BsGain is uniform over azimuth, 0 otherwise.
%   MSGAINISSCALAR  - this is 1 if MsGain is uniform over azimuth, 0 otherwise.
%
%   With 'polarized' option:
%
%   BSGAIN          - [KxSx2xNxM] array of interpolated antenna field
%                     patterns (complex), where the third dimension are
%                     the patterns for [V H] polarizations. 
%   MSGAIN          - [KxUx2xNxM] array of interpolated antenna field
%                     patterns (complex), where the third dimension are
%                     the patterns for [V H] polarizations. 
%
%   The ANCI-C version is develeped in WINNER project originally to
%   implement the 3GPP SCM.
%   To compile the ANSI-C written optimized core, type
%
%       mex scm_mex_core.c
%
%   at MATLAB prompt. For further documentation on the ANSI-C implementation 
%   of the WIM_CORE, see SCM_MEX_CORE.
