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! Max
