thankyou so much Alistu.
in that system, the rain rate has been fixed at ‘2’, how can i make this value variable??? for example : the formula i want to implement is attenuation = (3.91/v)(1550/550)^-q , where v is the visibility in kilometers and q is some number. so i will write this formula in th script of attenuation, but i want the values of v and q to be variable, that is they change according to some condition which will be specified in the matlab component that i will be attaching before the FSO channel.
how can i do this??
please suggest me a solution
regards
