The sensible way here is to realize that each complex sample has a magnitude z = ℜ z + j ℑ z = ( ℜ z) 2 + ( ℑ z) 2. In your case, the maximum non-clipping amplitude is 2 15 (the maximum-power samples are on a circle around the origin). Therefore, you'd calculate the magnitude of a sample, and compare that to 2 15 to ...
