relay system radio frequency and visible light comm

i want to make joint rf\vlc relay system same as in the paper but with some modification in it
1- first i want to modify equation 1 in the paper ,he add the signal from the Base station with the AWGN only without adding the interference from other base station so in this equation i want to search to get the new equation which taking into consideration the interference in RF Link
2- get the SNR in RF link , all calculation in AF (Amplify and forward) only
3- make same 1,2 in VLC Link
4- get the total equation gama equivalent of the total link from the source in RF link to the destination in the VLC link
5- make a q algorithm or any machine learning types algorithm to get the optimal path which have the highest SNR and maximum optical power(by matlab)
6- finally make some graphs to compare this work with monte carlo simulations
