I want to derive the phase noise profile for a given EVM thst satisfy certain SNR and Rx sensitivity.
How do I determine the classical phase noise please?
see paper tagged below ( I coudn't attach it for some reason) It shows evm plots for different anomalies in modulation process

There is no link to the paper. Could you please re-send? Thank you
I wrote a blog post: "Model Signal Impairments at Complex Baseband" that computes a QAM constellation with added phase noise. It also calculates MER (modulation error ratio). https://www.dsprelated.com/showarticle/1312.php.
Thank you. I shall look into this. To determine the classical phase noise of PLL from EVM, do you need to know the integration BW.
I understand that integration BW is a function of modulation BW, what is the rule of thumb for specifying it.
I haven't tried to calculate phase noise from EVM or MER. I used to measure the noise spectrum of the unmodulated carrier on a spectrum analyzer and record the noise density in dB (1 Hz) at the desired frequencies.
here is paper Vector Signal Analyzer Implemented as a Synthetic Instrument.
I can't attach paper,,, send me an email address and I'll pass it on

Hey fred, could you please email me a copy of the paper as well? I need to figure out why you are unable to attach it to your message.
