We propose two turbo-coded atmospheric optical communication systems: a turbo-coded atmospheric optical subcarrier phase-shift keying (PSK) system and a turbo-coded atmospheric optical pulse position modulation (PPM) system. We obtain upper bounds on the bit-error rate (BER) for maximum-likelihood (ML) decoding of both turbo-coded systems on atmospheric optical channels where the effects of the scintillation exist. We present the iterative maximum a posteriori probability (MAP) decoding of the turbo-coded optical binary PPM (BPPM) system. We show that both turbo-coded atmospheric optical systems have better BER than convolutional coded atmospheric optical systems when the Eb/N0with out scintillation is small. We also show that the turbo-coded atmospheric optical subcarrier PSK system has better BER than the turbo-coded atmospheric optical PPM systems. Moreover, we also show that as the scintillation becomes larger, the information bit energy-to-noise ratio Eb/N0 where the transfer function bound of turbo codes on the atmospheric channel diverges also becomes larger.
