Exoplanet terrestrials: fact or fiction?

Hot Jupitors exist for exoplanet systems; having been seen by radial velocity, and as transits. However for radial velocity oscillation patterns, with a wave function description, can't such wave function representation be broken down into a number of sets of component wave oscillations based on Fourier analysis? http://en.wikipedia.org/wiki/Fourier_analysis. Also can't a given radial velocity oscillations give combinations of different mass and distance for terrestrials? For example, in a simulation using our Solar system, together with various combinations of mass and distance for our terrestrials and Jupitor.
