We investigate how oceanic turbulence impacts symbol-error-probability of free-space optical communication systems operating underwater and based on phase-shift keying heterodyne coherent receivers. We make use of the oceanic turbulence power spectrum and we estimate symbol error probabilities for M-ary phase shift keying as a function of the normalized aperture of the receiver: D/r0.
