OFDM simulation using optical channel

[Rizbi HassanParticipant]

Hi there,

I am currently a 4th year student and am working on OFDM. I have written the Matlab code and its corresponding Optisystem file which acts as the optical channel. The problem is when I run the simulation, the receiver code is showing error “Subscripted assignment dimension mismatch” in line 25 n(1,:)=tx(1,:)

I am getting really frustrated as I have tried 100 times to solve this error. Please help me out with this code. I would really appreciate your help. Thanks.

Regards,
Rizbi

Hi Rizbi,

Can you please attach the two matlab .m files along with the project?

Thanks

Hi Damian,
Thanks for your kind reply.
I have managed to solve the problem but I think there is still some Error in my code. I am checking the BER for OFDM without using any optical channel. The BER shows 0 which is expected. But when I use optical channel, the BER still shows 0.
Please could you kindly take a look at my Matlab code? Thanks.

Regards,
Rizbi

Hi Rizbi,

I think I am still missing a function series2parallel and I cannot run the project.

i think the project isn’t complete , there is a missing part

Hi Damian,

Yes I forgot to attach the functions. Here are the series2parallel function. Please take a look at it now. Thanks.
