function param = setupParam(vdslDuplex);
%% ===========================================================================
%setupParam - Sets up the experiment description structure for
% a certain FSAN duplex experiment.
%
% Parameter:    vdslDuplex	String describing vdsl duplex method under test
% Returns:      param		Structure describing the experiment parameters
%
% Example(s):
%   param = setupParam; 
%
% Algorithmic details:
%   Fill in the ex.param structure according to default parameters and input
%   parameters.

% Change History
%      1998-10-19 (ToNo) Created
%      1998-11-13 (ToNo) Splitted setup into three parts param,tfplan,tt
%      1998-12-08 (DaB)  updated
%      1998-12-11 (DaB)  Added HAM band on/off (1/0)
%      1998-12-16 (DaB)  Added re_calc_bg_noise on/off (1/0)
%      1998-12-21 (ToNo) Moved efficiencyLoss into TF plans
%      1998-12-22 (ToNo) Updated comments
%      1999-01-05 (ToNo) Changed how modem under test was defined and
%                        added the possibility of precalculated noise models
%      1999-01-07 (ToNo) removed the duplex stuff (replaced by gui.testADSL/gui.testVDSL)
%      1999-01-18 (ToNo) Added DefaultMaxf as maxfrequency was set in evalExp.
%      1999-02-04 (DaB)  Added XTlevel for NEXT,FEXT,3CXT
%      1999-02-05 (DaB)  Added modemlist parameter for anaylsed gui.modems in evalExperiment
%      1999-02-07 (ToNo) Modified list
%      1999-03-05 (ToNo) Renamed and modified hamband to use ITU-HAMBAND
%      1999-03-30 (DaB) Corrected thirdCXT value
%      1999-08-11 (DaB)  Added Zterm
%      1999-08-12 (DaB)  New structure for efficiencyLoss different for ADSL and VDSL
%      1999-08-25 (DaB)  Added alpha
%      1999-09-30 (DaB)  Rewritten for new ex struct
%      2000-04-06 (UvAn) Added new param; expNoise
%      2000-05-02 (ToNo) Removed defaultMaxf as it was not used
