Abstract :
The feasibility of using Walsh-code-based synchronized CDMA (S-CDMA) technique to achieve multiple access in the presence of optical-beat and co-channel interference was previously demonstrated. In this paper, we propose adding an in-band clipping carrier to the SCDMA signal, to further suppress the residual optical beat interference (OBI) without using additional system bandwidth
