This work analyses the performance of a complete two-dimensional Optical Code Division Multiple Access system over Free Space Optics link under strong atmospheric turbulence. The system feasibility and performance is demonstrated through simulation with the commercial tool OptiSystem, from Optiwave, Inc. If a necessary component was not present in the software or its model did not correspond to the expectations, the desired device was created and programmed using the software MatLab. With the presented proposal, multiple users could share a single optical wireless channel, transmitting coded information for defense mobile applications. A usual optical sequence, called Prime Code, is used for both wavelength-hopping and time-spreading. The effects of variable distance, strong turbulence and different divergence angles are considered in terms of Bit Error Rate.
