Participanthi all,
can any one help about selecting the most approrpriate channel fading models for free space optics (FSO).
with regards

Participanthi asif,
As far as i know optiwave 14 uses gamma-gamma channel model by default. And i am not sure if we are able to change it to some other channel model. You can do one , just mail at optiwave customer support, may be that would help because as of now it is not possible to change the channel models in optiwave 14.regards

Participanthi aabid,
i was also using gamma gammma channel fading model. BUt i want to know if there any other model which better than than the gamma gamma.
if there is, how could i add that in the parameters of FSO in optisystem.
with regards

ParticipantWell i think may be you could do it in Matlab. May be you can write a program in Matlab and create a Matlab module in optiwave and just interface that created Matlab module with optiwave. You can check the updated version of optiwave 14 where they have provided with an option of interfacing Matlab modules with optiwave.

have you tried negative exponetial log normal channel ( reference book- wireless optical communication with matlab by s. rajbhanderi)?

Participanthi all,
thanks all for your valuable reply.but need how could i set the channel in the FSO of optisystem 14.AS we click on FSO component in optisystem, there are number parameters to be set. like various parameters which i have to set, channel model is one of parameter, i could i use matlab @aabid baba.
with regards.

ParticipantHi all..
well guys,I think we could just add a new module , i.e. the channel fading model only. The parameter of FSO channel could be turned off as if it didn’t exist. Then the MATLAB module could be called. This way I think it should work.

ParticipantHello Aasif bashir dar,
I am working on Channel Modelling in FSO considering the air turbulence, I wanted to use Gamma-Gamma Fading for the same. It would be of great help in my academics if you could share the code.
Thank you.
