QPSK BER for AWGN channel
Quadrature phaseshift keying (QPSK) transmission
StartThe simulation starts with a setting of ${E}_{b}/{N}_{0}=0dB$ (see marked line in the table below). This yields to this bit error probability:
Measured BER approximates the analytical bit error probability
${p}_{b}$
Analytical bit error probability
${p}_{b}$
for QPSK
ExperimentNow adjust ${E}_{b}/{N}_{0}$ . Measure the corresponding BER and compare it to the analytical bit error probability. Simulation ? Settings (F11)
Measured BER approximates the analytical bit error probability:
${E}_{b}/{N}_{0}=\mathrm{2,}\mathrm{2,}4dB$
