    Hi Mohamed Abouseif,
    Sir, I now face a problem in MATLAB Component.. I was working in my pc (Windows 8.1 OS). I have both matlab(2014 version) and optisystem 14.0… While including matlab file (.m file) in MATLAB Component, it was included successfully and i was able to run my osd file successfully.. Now i am working in my friend’s pc (Windows 10 OS). He has both matlab(2014 version) and optisystem 14.0… While including the matlab file (.m file) in MATLAB Component, it was included but I cannot able to run the osd file. It showed me this error..
    CIDF Scheduler:ERROR OCCURED WHILE CALCULATING MATLAB COMPONENT..
    ERROR IN MATLAB COMPONENT.. ERROR LOADING MATLAB ENGINE..
    CALCULATION FAILED

    How to solve this problem sir??

    Hi Mohammed,
    The paper you provided helped me to gather points for my review. But Sir, I have prepared the Encryption and Decryption codes for the steganography (data hiding in image) part. Now my requirement is, How can I able to decrypt back my original text message from the received signal (electrical output signal) at the optical receiver? Is it possible to convert the electrical signal to some format to get back my original text message? SHOULD I NEED TO SAMPLE AND QUANTIZE THE OUTPUT ELECTRICAL SIGNAL OF OPTICAL RECEIVER?? Please help me in this section.

    Thanking You.

    Hi Mohamed Abouseif,
    Sir, I have changed the MATLAB component output port to binary. Now my problem is, I have to convert a string or image into binary format through matlab code and give that binary as an input to duobinary precoder. I have written a sample code which converts a string to binary. I have imported the code into MATLAB component and I want that MATLAB component to act as data source for duobinary precoder. I don’t know whether the code i have written gets fitted into the MATLAB component correctly or not.. also i don’t know what should i have to give as input to the input port of MATLAB component.. I have attached osd file and two matlab codes that i have tried.. please help me to solve the problem.. Thanking you
