Performance Evaluation of OCDMA Over Free Space Nonlinear Channel
In this research, we numerically simulate the wireless OCDMA system to measure the system performance for
non-coherent optical code with seven simultaneous users. The influence of atmospheric wireless channel effect on bit rate
and channel length was analyzed. In our analysis, the noise cancellation was performed by digital signal processing
algorithms theoptimal channel length according to input and received optical power 1100m, system performance was tested
using BER and eye diagram standards.
