Let suppose we have equation of received signal r=hd+n where h is for fading channel , n is awgn channel and d is signal transmitted. Now the signal received is denoted as r. I need to write equation in which I can also receive the position (x,y) of mobile node let suppose that the node is equipped with GPS receiver. Where x and y may be latitude and longitude of that node. Should h fading parameter will be multiplied or like this r_postion=hx+hy+n or what?

Please guide
