Hi Marvi grover,
can you please upload the optisystem design file. I am also going to implement in this way as you are doing.

Hi Ranjeet thank you for providing with the links. i need to look into this matter. From today onward to do my research works.

Hello Fayiqa Naqsbandi,
I am trying to design the wireless portion using MATLAB simulation platform and there is no wireless portion components in optisystem, presently I am not getting a fruitful output for the MATLAB code that I need, in most of the technique that i found online from MATHWORKS are for very low data rate. But i want to have as much as possible as everyone needs.. mimo channel i want to use if possible spatial diversity technique.

Hi Aabid baba,
I am doing now the matlab coding taking into consideration of Rayleigh as well as rician fading channel, I have got may examples regarding wireless rayleigh fading channel that uses BPSK modulation format. I am attaching herewith a MATLAB code. so can you modify the file to integrate to optisystem taking anyone of the example using QAM modulation scheme that is available in the samples folder. please have a look into the .m file. Thank you in advance.

Hi Ranjeet Kumar,
I think you are not getting what I am looking for, I need to design fiber wireless system where the wireless portion need to be for normal common uses such a broadband wireless access, again and again i am suggested to go for free space optics but at this point of time I dont want to implement FSO because FSO is not useful in case of uses such as mobile broadnd. Thanks for the response..

Hi Dhiman, Thanks for providing me with the block diagram which I was looking for. I think the wireless portion is going to be a tough job to implement as seen from these block diagrams. anyway thanks a lot. Hope to get more help in future posts.

Thanks Alistu for the suggestion. I will definitely look into this matter.. hope to get more help in future design problem which i will be facing.

Hi Prakash,
I can see FSO advantageous where there is no possibility of laying optical fiber (point no. 6) and in terms of cost otherwise all the factors are you mentioned are available in fiber link. and line of sight is most important in this case so this technique is advantageous in some of the specific case only. Thanks for providing with some useful important points.

Hi Alistu,
I do not want to use FSO here as it has some major drawbacks such as its performance is weather dependent i.e. in case of rain or some other parameter this system quality degrades. and one more issue is that there is a need for high accuracy in the alignment i.e. direction is of more concern so for these disadvantages i do not want to use it.

furthermore the design file in the issue you have referred these results are for only 0.5m which is very less and and we need it in terms of km range in free space optics.
Thanks for the reply.

Hi aabid Baba,

Thank you for the response, the paper you have attached is very much helpful in the field of research of radio over fiber, but for the wireless portion mainly the results are shown, and do not have a detailed explanation which I am looking for.

Hi Nazira,
I am unable to find the link you are referring in the above reply #30930. please reattach again. at present state i am worried about the wireless part. so I was basically asking here for the block diagram that would be very much helpful in case of Radio over Fiber fi-wi system. Thanks for the response.

Hi Nazira,
Thank you for the reply, and putting one of the most important point more specifically about the mm wave that is used in the electrical domain and multiplied with the bit stream and then the combination is used to the electrodes of the modulator to have it in optical domain.

Hi Prakash,
Thanks for the response, You can refer to any of the design that is there in the OptiSystem 14 samples in the “Microwave or RF optical system folder”, I basically need the block diagram for the wireless part, then it would be helpful for writting the codes.

Hi Aasif,
Thanks for the reply, I want to do MATALAB optisystem co simulation, and want to design wireless design in MATLAB and integrate in optisystem.

secondly i do not want to use the Free Space Optics (FSO) in the design as it has two big disadvantages such as its performance is weather dependent i.e. in case of rain or some other parameter this system quality degrades. and one more issue is that there is a need for high accuracy in the alignment i.e. direction is of more concern so for these disadvantages i do not want to use it.

[Prarthana KashyapParticipant]

Thanks Alistu for the reply. I will look deep into this matter.
