query about NLOS channel and modulation schemes

[sheikhsaadi]

Hello developers,
I'm an telecom engineering student and im working on my final year project in which i have to implement a VLC physical channel both LOS and NLOS for various adhoc networks. your module has greatly helped me in my project as it is performing what i want and i thank you for that. my queries are that:

1. your module is only implementing the LOS channel but i want to implement the LOS and NLOS both and then also see there combine effect so what should i do to implement the NLOS channel.
2. secondly you have performed the BER and SER for OOK,PAM and VPPM, but i cant figure out that where has the actual modulation taken place? I mean that if OOK is being implemented so where is the code in which the input bit are being modulated and then being transmitted because BER is calculated at the receiver end so the bit have to be demodulated first.
   so please help me in figuring out this problems as im really stuck at this moment and im running out of time.
   thankyou so much.

Hello sheikhsaadi,

The non line of sight (NLOS) is already scheduled to be implemented into this module. In order to get an idea of the NLOS, please refer to Wireless infrared communications and Fundamental analysis for visible-light communication system using led lights.
Regarding your point #2:
The modulation/ demodulation blocks are implemented for PSK and QAM at this time which will be released in few days ( third version of this module). To understand how these modulation work (the one you mentioned above) , please look at the doc file in this module. once I release the last module you are welcome to extend it as your project requirement.
Please use asa52@njit.edu to contact me if any other questions.
Thank you.

hello Adel, I have been trying to run the 2nd module of yours in which various modulation schemes are being implemented but Im always getting a certain error(screenshot attached) due to which the example is unable to run. please see this error and guide me accordingly and please explain a little in detail that in which file whether the model or the example should i troubleshoot to correct the error. urgent help required.
