The preparation of MATLAB M-file, use the document on the use of envelope detection demodulation system 2ASK anti-noise performance of the 1000 Monte Carlo Simulation of symbols, drawn between error rate and signal to noise ratio curve, which SNR value for r = 0dB, 2Db, 4Db, 6dB ... ... 10Db, bit error rate at the same time draw the theoretical curve with the signal to noise ratio, signal to noise ratio value for one of r = 0dB, 0.1dB, 0.2dB , 0.3dB ... ... 10Db
