If you only want to draw a 3x3 grid of 1x1 squares this is pretty easy (see below). If you want the 0.75x0.75 and 0.5x0.5 squares also but not interlocked as your image shows just wrap this code in another loop. If you want them interlocked (sometimes the green is on top of the blue and sometimes vice versa, for example), it is going to be much harder. I'm not even going to try right now.

for x = 0:2
    for y = 0:2
        rectangle('Position', [x y 1 1], 'EdgeColor', 'g', 'LineWidth', 2)
    end
end
axis equal
axis 'off'

I don't know what you mean about placing "transmitter and recievers at desired places". Also, it is unclear what you mean by "scenario".
