| 3 | 1 | ABDALLAH, Hussein | For a beginner of LABVIEW, The first step of simulation is building a BPSK communication chain with Gauss White Noise channel and without coding. |

| 9 | 2 | ABDALLAH, Hussein | Like the figure above, we first generate the pseudorandom series bits “0” or “1”, then use BPSK modulation, we make “0” with 0 radian phase, and “1” with pi radian phase. Put signal through the Gauss White Noise channel, of course the noise comes out through the Eb/N0 calibration module, the next step is BPSK demodulation, use it to recovery the information bits, then the last step if calculate the BER. According the different Eb/N0, we get the different BER, the we draw the BER curve as a function of Eb/N0, |
