Change the PDSCH allocation to span PRBs 0 to 10. Generate the waveform and plot the spectrogram. Get waveconfig.PDSCH{1}.PRBSet = 0:10; [waveform,waveformInfo] = nrWaveformGenerator(waveconfig); % Plot spectrogram of waveform for first antenna port samplerate = waveformInfo.ResourceGrids(...
This reference signal is modulated by a PRBS6 phase modulation that is used to measure the closed loop phase noise transfer function of the PLL. The input spectrum is evaluated by a spectrum estimator.The output spectrum is measured both by the PLL Testbench and by a spectrum estimator like ...

6.2.5. How can I make spectrum plot without confidence intervals? If you are using the spectrum/specplot functions in the Signal Processing Toolbox, and you do not want the confidence intervals plotted along with your PSD, you have two options: 1. Use the psd and csd functions, instead....
We can get a quit good electrical spectrum with a high OSNR. Even with such high OSNR, the constellation and ber are not good. The problem maybe is the bug of the co-simulation MATLAB code. The code at the received maybe has a wrong de-modulation to the ofdm signal. ...
