The heterodyne systems with polarization modulation presented so far are reviewed both from the theoreti-cal and experimental viewpoint. The probability distribution for the basic schemes is determined through a rigorous derivation. Consequently the detection sensitivity for these particular cases is shown equal to that of FSK (although with reduced bandwidth occupancy) . This fundamental equivalence is also extended in a qualitative way to all the configurations using orthogonal polarization vectors for modulation. Open problems regarding the analy-sis of advanced versions and the development of numerical simulations are also discussed in detail.
