ParticipantHi 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,

ParticipantHi 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,
