OFDMA 物理层开发的matlab 源码.飞思卡尔提供.对物理层开发的工程师有帮助!

% Uplink Tx (MS) chain of user processing of IEEE 802.16-2004
% (WiMAX, OFDMA only) 
%
%     [SlotVecs] = UPULTXchain(In,SlotVecs,ZoneD,BurstD)
%
% This function chains up all the required Matlab functions and processes
% the payload data of one burst (In). After modulation mapping the data is
% mapped into the defined data region of the zone (SlotVecs).
%
% In      : input vector, payload data for one burst
%           (unsigned bytes, values 0 or 255)
% SlotVecs: input/output matrix that is the interface to FP (complex)
%           one column per slot vector, 48*ZoneD.NumSubch rows
% ZoneD   : zone descriptor
% BurstD  : uplink burst descriptor
%
% Matlab 7 Release 14 SP2
% The communication toolbox is required.
