We propose atmospheric optical code-division multiple-access (CDMA) systems. We analyze the bit error rate (BER) of the proposed system using pulse position modulation (PPM) with considering the effects of the scintillation, avalanche photodiode (APD) noise, thermal noise, and multi-user interference. We show that the atmospheric optical CDMA systems can realize communications at the bit rate of 156 Mbps when the log-arithm variance of the scintillation σs2 is smaller than or equal to 0.1. When σs2 is large, we need to use forward error correction codes (FECs).
