Apply pulse amplitude modulation (PAM) to the generated data. Employ a Gray-coded symbol mapping order for the modulation. modData = pammod(dataIn,M,0,"gray"); Pass the modulated data through an additive white Gaussian noise channel. Set the signal-to-noise ratio to 8 dB. ...
I think it can be done much more elegant by performing a FFT at a single frequency, in this case "fl". But I have to think about it and if I get a solution I will come back later.The
A Random Integer Generator block generates integers in the range [0,15] for a modulator configured to apply 16-QAM. The modulated signal passes through an AWGN channel, and a constellation diagram displays the resulting symbols. Run the model with Eb/N0 set to 20 dB in the AWGN channel. ...
This terminology is also used by MATLAB, so in this text the term “vector” translates to “sequence or array of numbers” often representing a time signal. Time slicing samples the continuous waveform, x(t), at discrete points in time, nTs, where Ts is the sample interval and n = 1...

MATLAB Simulink models are formed to generate the multilevel modulation formats, transmission, and detection in optically amplified fiber communication systems. Transmission performance is obtained for the multilevel optical signals and proven to be equivalent or better than those of binary level with ...
Subjects achieved a median speech reception threshold (SRT50%) of 5.7 dB (range: − 3.0 dB to 15.6 dB). Subject 1038 could not complete the Oldenburg Sentence Test (OLSA) because the maximum SRT50%of 25 dB was exceeded, so this subject was excluded from all analyses comparing the speech...

To avoid loudness cues resulting from changes in AMD, the unmodulated and modulated stimuli were energy matched by adjusting the RMS amplitude to a constant value. Additionally, level roving was applied in the psychoacoustic paradigm with a range of ±3 dB to reduce the usefulness of any ...
Add white Gaussian noise such that the signal-to-noise ratio is 20 dB. Reset the random number generator for reproducible results. Use the periodogram function to estimate the power spectral density (PSD) of the signal. Get rng default SNR = 20; noise = randn(size(x))*std(x)/db2mag(...
