MATLAB-functions used in Space-Time Project Simulation

function [outdata_block]=add_training_mult(data_block,training_seq)

%   [outdata_block]=add_training_mult(data_block,training_seq)
%
%	Output:
%	outdata_block	    - Training sequence and datablock (symbol-vector)
%	
%   Input:
%   data_block          - Alamouti-coded symbols. (symbol-vector)
%   training_seq         - training sequence 
%   
%   
%
%   Short Theoretical Background for the Function:
%
%   Instead of adding binary training-data to the original data-sequence, 
%   this function adds bpsk symbols after alamouti-coding is performed
%   so that the training-sequence will not be alamouti-coded.

%   2.0 SU  2001-04-04  Adds bpsk-symbols to data. Function supposed to be called
%                       after that Alamouti-coding already has been performed.
%                       This function uses the model parameter and adds two
%                       training-sequences when a 2x? is used.
