In Optisystem i have tried to xor to binary signal and send them through optical fiber.At receiver i found the o/p wtih good q factor.how i can detct those 2 oregional signal form the detected xor signal.

Dear Jagan,
Adding to the above colleagues, if you have x-ored two binary signals x and y, then the output is :
z= y x-or x,
in order to get for example the y signal one has to x-or z with x and in order to get x from z one has to x-or it with y. This is straight forward from the basics of the Boolean algebra. So, having z only you can not get y and x. This can be predicted from the x-or operation it self. The x or function is zero when the y and x are equal and equal one when they are different.
Concerning the bi phase encoding it is so that the logic one is represented by positive pulse followed by a negative pulse while the zero is represented a negative pulse followed by a positive pulse. the two symbols are shifted by 180 degree.
Concerning the type of the digital modulation technique that needs x-oring is DBPSK, the differential binary phase shift keying ,where the current symbol is referenced to the previous symbol.
Wish you success
Hi jagan, you can use Binary visualizer to detect recovered data and compared it with the original signal individually. At the receiving side, you also need to convert the electrical signal into binary signal.
