% 802.16-2004 OFDMA PHY - mFPULTxHarness Uplink function
%
%    Description:
%           Matlab function for simulating subscriber station Tx (UL)
%           freq. domain processing
%
%    Inputs:
%         ZoneConfig: Data Structure that contains zone configuration
%                     params, including number of carriers, number of
%                     used carriers, maximum number of subchanels, etc.
%                     For details please see WiMAX Integration Framework
%                     Specification document
%       AsyncPhyCtrl: Asynchronous PHY control data structure
%                     contains info such as UlPremableBase IDCell, etc.
%        SymbolIndex: Symbol index within frame of the first OFDMA symbol to
%                     be output.
%           inp:      one slot vector coming from UP
%           TC:       test case number
%           write_tv: enable (y/n) to write test vectors
%     scrambl_enable: enable (y/n) to scramble data and pilot carrier
%                     positions
%
%    Output:
%           Out:      Three OFDMA symbols, each NFFT long
%
%    Data Files:
%                N/A
%    Functions/scripts:
%                GenerateULTable
%                mGenPRBS
