Hello Marc,
In MATLAB R2023a, the function comm.EyeDiagram() has been replaced with the function eyediagram(), which is mainly used for visualizing the signal. However, you can use the new function comm.JitterAnalyzer() to analyse the jitter in your signal and obtain metrics such as eye width and height.
To use comm.JitterAnalyzer(), you can pass the signal data as input and set the appropriate parameters, such as the symbol rate, the reference level, and the jitter tolerance. The function will then analyse the jitter in your signal and output the relevant metrics. Eye height and width can be calculated using the jitter analyzer.
Here is a example code for your reference.
% Generate random signal
data = randi([0,1],1000,1);
% Create modulator and demodulator objects
mod = comm.BPSKModulator;
demod = comm.BPSKDemodulator;
% Modulate and add noise
modulated = mod(data);
noisy = awgn(modulated,10);
% Analyze jitter
analyzer = comm.JitterAnalyzer('SymbolRate',1,'ReferenceLevel',0,'JitterTolerance',0.2);
jitterMetrics = analyzer(noisy);
% Display results
disp(jitterMetrics.EyeWidth)
disp(jitterMetrics.EyeHeight)
Hope this resolves your issue.
