Topic: DPSK SIGNAL GENERATION
I need RZ-dpsk signals as input in my system. Can anyone help me out to generate DPSK signals in optisystem ? How to generate them ?
Hello Everyone,
First of All thank you all for responding so well to my previous query.
Actually i want to plot a Spectral efficiency vs Signal to Noise Ratio (SNR) curve for different advanced modulation schemes such as BPSK, DPSK, QPSK, QAM, MSK, M-Ary etc.
Is there any provision to directly plot the curves of all the modulation schemes mentioned above.?Thanks
Regards

hello everyone
I want to dpsk demodulator. but it is not avaliable in optisystem. Please tell me the alternative.

Hi Everyone,
I want to design Ultra Dense Wavelength Division Multiplexing System using different advanced modulation formats like CSRZ, DRZ, MDRZ and DPSK and DQPSK.
My aim to design above system with channel spacing 50GHZ and 25GHZ.
I have design the above networks for 100GHZ channel spacing using symmetrical compensation technique and at a bit rate of 40gbps and for long haul communication i.e upto 1200 Km.
Here i am uploading 32 channel WDM system with 100ghz channel spacing system at 40 gbps bit rate and using symmetrical compensation technique. But when i decease the channel spacing upto 50ghz and 25 ghz, we doesn’t find results at BER analyzer, although it works for channel spacing of 75ghz.
So, I request you to suggest some techniques or steps to get it.
Here I am uploading an osd file of 100 ghz channel spacing CSRZ DWDM system.Seeking your response.
