Run the model with the Eb/N0 of the AWGN Channel block set to 15 dB. The constellation diagram shows the QPSK symbol samples with AWGN. Change the Eb/N0 from 15 dB to 10 dB. The noise level increases as shown by the greater distance between the samples in the constellation diagram. Vi...
aFor OFDM with QPSK simulation, constellation diagram of transmitted signal and received signal is shown in Figure 5. The OFDM with 8-QAM and 16-QAM mapping simulation are analyzed for BER performance and compared with 8-PSK and 16-PSK systems simulation as shown in Figure 6. 为OFDM以QPSK模...
QPSK-modulate random data symbols and apply an amplitude imbalance to the signal. Pass the signal through a noisy channel. Display the resultant constellation. Create a constellation diagram System object. Because the default reference constellation for the object is QPSK, setting additional properties ...
data = randi([0 3],200,1); modData = qpsk(data); txSig = txfilter(modData); You can display the constellation diagram of the transmitted signal usingscatterplot. Since the signal is oversampled at the filter output, you need to decimate by the number of samples per symbol so that ...

As already mentioned, the constellation diagram has a very intuitive utility for judging the bit error rate of modulation schemes. Next, we use Matlab for QPSK (M=4) modulation to give an example to illustrate: respectively, select the signal-to-noise ratio of 0dB, 10dB, 20dB, at the ...
A new method is proposed to set the modulation errors of the output digital modulation signal from vector signal generator accurately based on constellation diagram design.The theoretical derivation,implementation of the method and experimental verification are presented.This method can be used not only ...
