[Communication-Mobile] vij1 DL : 0: 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

[Other] MATLAB DL : 0: A 2by3 MIMO model using Simulink. The decoder uses zero forcing algorithm. Set in the workspace the modulation order (QAM modulation), Doppler shift, SNR in dB, bit rate, sample per frame, max number of bits and max number of errors before running the simulation. Works also with BERTool but change the BER variable to ErrorVec. Included in the file a BER session with multiple runs and a figure for several runs.
