Do you have an experience of actual measurement of BER using actual instruments not EDA-Tool-Play ?nassim1 said:I mean in microwave field ........
It seems you don't understand basics of simulation at all.nassim1 said:Is there any cicruit simulation in ADS software ? how can we make the cicruit to simulate the BER ?
This uses Ptolemy and Logic Analyzer.nassim1 said:I have Application Note Number 1471 'Agilent Technologies RF/IF-to-Digital Connected Solutions Bit Error Rateusing the Advanced Design System '
I don't think you can say you are working in RF receiver.nassim1 said:I'm not working in Digital domain and since i'm working in RF receiver
nassim1 said:i think is better to have an idea BER..
Isn't it ??
Just same as actual measurement.nassim1 said:4. Again i'm asking how can we make the simulation of BER in ADS and aloso for practical setup.
It is a very easy application note.nassim1 said:5. i saw in application note Number 1471 of Agilent some explanation on BER which is also interesting as document...

Do you understand two simulation domains in Agilent ADS ?
Consider actual measurement unsing actual instruments not EDA-Tool-Play.
What instruments or systems are required ?
What systems are included in your DUT receiver ?
What type of modulation is used in your system ?
Does your receiver include data decision circuit ?
Simulation conditions are very different with your receiver conditions.
Do you understand "Receiver of Digitally modulatged RF signal" ?
I think you don't understand basic concept at all.
Again see the following surely.

Do you understantand it ?
It can not be.nassim1 said:2. In the site of Nec, they provide the model of the transistor which can be used in ADS but unfortunatly that model does not work. Could you check it if you have time ? you will see that i am right that why i asked for another way to use transistor model.
Simply you don't understand usage of netlist in ADS.nassim1 said:1. For the netlist in ADS, yes i konw how we use it but still have pb to verify the obtained model, i.e, when i wanted to check the bias, it does not work...
If your receiver is for 2-FSK and signal detection scheme is limiter and data slicer, data decision circuit or data slicer is needed.nassim1 said:Does your receiver include data decision circuit ? I don't understand this question..
If you can understand Digital modulation RF RX/TX system correctly, answer is self-evident.nassim1 said:Simulation conditions are very different with your receiver conditions!!. How ?
So does your receiver include I/Q-demodulator ?nassim1 said:In my receiver, there are BPF, LNA, Oscillator, Mixer and LPF
See the following.nassim1 said:QAM, I want to generate BER curve and then compare it the ideal BER curve of for example the standard 16 QAM...!!
No. It means plumbum generally.nassim1 said:2. Pb is familiar abbreviation. it meas Problem
See https://www.designers-guide.org/Forum/YaBB.pl?num=1238705966/3#3nassim1 said:Also, what about if the receiver assume quadrature sampling using single ADC ?
Simply due to lack of your basic knowledge.nassim1 said:It is not well explained.......Really, i could not understand
See https://www.designers-guide.org/Forum/YaBB.pl?num=1273409182/11#11nassim1 said:It remains, the verifications of s-parameters btween s2p and those obtained by NecActive_library.
