i mean i have plotted the graphs for Q-Factor

[Anamika BasnotraParticipant]

hi, Alessandro
I am done with plotting the graphs for Q-Factor

[Anamika BasnotraParticipant]

Hi, Ravil
even i was thiking of this substitution bt was not sure.
you cleared my doubt. thankyou

[Anamika BasnotraParticipant]

hi, Sam Sung
the problem that i am facing is not the calculation but the representation
i have already calculated the BER; now i have to plot the graphs
for that i have to change the exponential form of BER into normal form
one of the way is to convert it into negative log
But since some of the values have come 0; so they cannot be converted.
i am asking; is there any other way in which i can represent BER in normal form (without exponents)

[Anamika BasnotraParticipant]

thankyou Ravil and Sethi sir

[Anamika BasnotraParticipant]

hello sir
some of the journals ask for ‘suggested reviewers’. can you explain what does that mean?

[Anamika BasnotraParticipant]

n thankyou; i understood your point which you tried to explain.

[Anamika BasnotraParticipant]

i cannot upload my original file on which i am working
bt for reference i have uploaded another file
can u check this file
when we simulate this for the first time, it will not give any output
then if we change the bit sequence to pseudo random, it gives the output; this point can be understood
but if we again change the bit sequence to user defined, this time it gives the output. can you explain this point?

[Anamika BasnotraParticipant]

can this problem be solved by using user defined bit sequence generator??

hi, Gherbi Mohamed
you can try removing amplifier from the loop
and check the result, bt may be results wont be displayed or the o/p may be worse.
its always preferable to use amplifier with DCF.

[Anamika BasnotraParticipant]

thankyou so much sir

[Anamika BasnotraParticipant]

thnkew Mr. Sethi
u cleared many of my doubts
bt the link which u provided doesnot match any of the paper in the IEEE library
can u provide some more information; it will be really helpful

[Anamika BasnotraParticipant]

the loop is used in the system if u are using the components like amplifiers in ur setup
eg. if u r using an amplifier and u are using a loop control with it, and keep the no. of loops as 3. that means u r amplifing ur signal 3 times

[Anamika BasnotraParticipant]

yeah ofcource Rvail
the thing introduced in this fiber is ‘cross phase modulation’
the doubt here is why is CWDM written with its name. it must be having some special significance
n if u get to know anything related to this, plz let me know
