how to take VLC channel in matlab

i don't have any code

[Jan]

Please explain any details. What are the available inputs? What does "take a VLC channel" mean? What do you want to get as output?

i want to transmit the image through VLC(visible light communication) channel.here transmission technique is OFDM. can you explain how to generate channel matrix for VLC.

[Jan]

Oh, I thought you want to grab a transmission from the VLC player (Video Lan Client).

Now explain: what is "the image"? What does "transmit" mean in your case? From where to where? Why is the transmission technique important? What is a channel matrix?

Please explain how your problem is related to Matlab.

this is related to optical communication.i attached the block diagram for that.i want to develop the code in matlab. here how to take VLC link in matlab i don't know. can you please tell me

@MAMATHA YADAVALLI: Your question is far too general to be answered in the forum. At least I do not have any idea about "how to take VLC link in matlab". I'm even not sure if this is a software question, or if you want to control some external hardware to transmit the data.

If you want somebody to develop the idea in detail and write the complete code for you, you have to hire a consultant.

suppose for awgn channel matlab command is H=awgn(input data,snr,'measured'); input data is output of the IFFT,snr value is 14 likewise for optical(VLC) channel what is the command to take the channel matrix.

MAMATHA YADAVALLI did you get the methode of how to modulate a VLC channel in matlab , cause I am interesting on the paper containing this image and I don't know how to reproduce the same results in matlab (I mean I don't know how to modulate a VLC channel in matlab). so if you have any thing that help us , could you please share it here?
