%  802.16-2004 OFDMA PHY - mFPDLTxZoneInit Downlink function
%
%    Description: Initializes LUTs that are constant within the zone.
%
%           [DlCarrierMap,PRBS] = mFPDLTxZoneStart(ZoneConfig,
%           AsyncPhyControl)
%
%    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.
%
%    Output:
%           DlCarrierMap: Scrambling LUT (includes the cluster,subchannel
%                 and carrier permutations)
%
%           PRBS: Psuedo random bit sequence that is used by the Data
%                 modulator. (consists of 32 more bit than required to
%                 cover all teh possible offsets.)
