%  802.16-2004 OFDMA PHY - mFPDLTxHarness Downlink function
%
%           [NFFToutToTP] = mFPDLTxHarness(ZoneConfig, AsyncPhyControl,...
%                           DlCarrierMap, PRBS, PayLoadFromUP, SymbolIndex)
%
%    Description: Main function for the downlink Frequency Domain
%    processing in OFDMA (8.4) of IEEE802.16e standard
%
%    Input:
%           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
%           AsyncPhyControl:Asynchronous PHY control data structure
%                       contains info such as DlPremableBase IdCell, etc.
%           PayLoadFromUP: Information elemnts recieved from the User
%                       Processing, organized as a slots vector, with Nx48
%                       datums. N depends on the FFT size. This info
%                       vector is mapped into 2 OFDMA symbols.
%           SymbolIndex: Symbol index within frame of the first OFDMA symbol to
%                       be output.
%
%    Output:
%           NFFToutToTP: Output 2 OFDMA symbols for data or a single
%                       Premable symbol. In each case the output is a full FFT sized.

%    Functions:
%                N/A
