Currently, I am using the below code to display the spectrum of the received signal (before receive filtering) using dsp.spectrumAnalyzer. However, I need the data that is shown itself. How can I get it? Also, how can I generate the spectrum as dsp.spectrumAnalyzer manully from sctractch using fft?
data = 2.*randi([0 1], 1e6, 1)-1;
txFilter = comm.RaisedCosineTransmitFilter;
filteredData = txFilter(data);
rxSignal = awgn(filteredData, 20);
freqAnalyzer = dsp.SpectrumAnalyzer('SampleRate',8e6);
freqAnalyzer((rxSignal));

Hi!
data = 2.*randi([0 1], 1e6, 1)-1;
txFilter = comm.RaisedCosineTransmitFilter;
filteredData = txFilter(data);
rxSignal = awgn(filteredData, 20);
freqAnalyzer = dsp.SpectrumAnalyzer('SampleRate',8e6) ;
freqAnalyzer((rxSignal))
specData = getSpectrumData(freqAnalyzer) ;
figure
plot(specData.FrequencyVector{1,1}, specData.Spectrum{1,1})
Hope this helps
