Hi All
I want to know if there is any provision of plotting a graph between bit error rate versus signal to noise ratio for diffrent users?
Answers will be appreciated.Thank you

HELLO DOMAIL..
I don’t know about the SNR vs BER but we have the provision to plot different parameters versus different parameters.. I suggest you to check the Options in the global parameters of graph section.. May be that will help..

Hello Domail,
I completely agree with Fayiqa. This is a provision. I have come across about it on the forum itself.Regards

HI SHAFEEN..
I am not sure but i think there is..I shall look for that thread where i had seen it..Will be posting the link soon.

Hi Domail,
I guess in optisystem,we do have a provision for this..

Hi Deepak,
Are you sure that we have a provision for this in optisystem ?

Hi Domail singh ,
I think we don’t have an option to plotting graph of BER against SNR directly.
There is a relation between BER and SNR, if the noise power is fixed,
the signal power wiil decrease proportional to the square of the distance.
factor on which BER depends are where P0 and P1 are the probabilities of the symbols, M is the number of samples for the logical 0, and N is the number of samples for the logical 1, average values and standard deviations of the sampled values respectively, and S is the threshold value.If the signal is mixed with the noise, the Average Gaussian method is modified to calculate the average error patterns.
For relation between SNR and BER, i am posting the links:

http://www.radio-electronics.com/info/rf-technology-design/ber/bit-error-rate-tutorial-definition.phpThe BER result is plotted to the
right for various SNR values as in figure :Thanks and regards,

HI RAJGURU..
He is i guess looking for something else..I think you must reread the query.

HI ALL..
Here i am posting the link where i had found that we can plot a graph between SNR and BER.. I hope this would help you.
