function [training_sequence]=random_training(sequence_length)

%   [training_sequence]=random_training(sequence_length)
%
%	Output:
%	training_sequence	- Random training (zeros and ones)
%	
%   sequence_length     - Desired length of training sequence (Preferably an even number)
%   
%   Short Theoretical Background for the Function:
%
%   A deterministic training sequence with better autocorrelation properties
%   is usually a better solution than this random one.
