Communicating polarization-dependent information over a free space channel may include separating a data signal carrying data into a first signal and a second signal each carrying a portion of the data of the data signal, modulating a first carrier signal with the first signal and a second carrier signal with the second signal, radiating the modulated first signal with a first polarization as a polarized first signal over a free space channel, radiating the modulated second signal with a second polarization as a polarized second signal over the free space channel, demodulating the polarized first signal and the polarized second signal, and combining the demodulated first signal with the demodulated second signal to provide an output signal carrying the data of the data signal.
