Dear Sir,
please how can i design a subcarrier intensity modulator (BPSK-SIM, DPSK-SIM)in optisystem 20demux 1×4 not able to connect to DPSK Tx and Mux 4×1 not able to connect Dpsk Rx
Topic: Radio Over Fiber
Hi all
I am working on radio over fiber using SCM/WDM with DPSK and CPFSK schemes, I am analyzing the effect itteration of fiber length and bit rate. But i am having some problem in getting the correct output can you please help me to rectify my problem?. My project simulation picture is attached with this query.Topic: M-ary threshold
Hello everyone
Does anyone know How to determine the threshold and output amplitude value at M-ary threhold?
In https://optiwave.com/resources/applications-resources/optical-system-digital-modulation-dpsk/ the defined threshold amplitude value is – 0.85, -0.353, 0.353 and 0.85. I don’t understand how that value is obtained

Hello everyone

I didn’t understand why in this link (https://optiwave.com/resources/applications-resources/optical-system-digital-modulation-dpsk/) the defined threshold amplitude is – 0.85, -0.353, 0.353 and 0.85?
Dear all
Hope you all will be fine
Please let me know how to generate DPSK and PAM signals in optical domain using Optisystem?Please post .osd file or screen shot of the simulation please
regardsTopic: Cutoff frequency of LPF
I am using LPF at the receiver terminal in 2.5 Gbit/s FSO link. Can someone please tell me what should be the cutoff frequency of LPF? In some example it is 0.75*Symbol rate and in some examples it is 0.75* bitrate. I am using NRZ and DPSK modulation schemes. The Q factor varies greatly if i change from symbol rate to bitrate
Thanks in advance…
Can anyone please explain the transmitter and receiver section of DPSK modulation?
Hi, everyone. I’m working on a system which need generate OSSB (Optical Single Side Band) singnal with LiNb MZM using DPSK modulation.
Can you help me? Thanks very much! (Optisystem13 preferred)
