Abstract
In this paper, a turbo-coded optical interleave-division multiple-access (OIDMA) scheme is studied. A maximum a posteriori (MAP) based asynchronous on-off keying (OOK) MUD algorithm is proposed. Besides, system capacity is analyzed with an iterative technique called SNR evolution. BER is evaluated over log-normal turbulence channels, taking into consideration the effects of thermal noise and background noise. Simulation results show that the proposed OIDMA scheme has good convergence property and low BER performance. Moreover, the related interleaver-based iteration MUD algorithm is quite robust in the asynchronous scenarios.
