function ber_ml=Alamoudi(snr,soglia); 
 
%This function simulates a Alamouti scheme. The input variables are soglia and snr. 
%Soglia: is the number of errors after which the iterations stop. For better results, put high value of soglia, but 
%the simulation is longer. 
%snr: the signal to noise ratio (if u don't know what is a signal to noise ratio, well, come back to your high school!). 
% 
% 
%Note: U should use this function with a main function in wich u chose different value of snr. That's because this 
%function work just with one value of snr. 
% 
%If u have problem with this code, write me at m.allegritti@email.it. 
% 
%Take care!
