Generation of a new hybrid subcarrier multiplexing-SAC-OCDMA system based on FSO

Abstract

This paper proposes hybrid Subcarrier Multiplying-Spectral Amplitude Coding-Optical Code Division Multiple Access system (SCM-SAC-OCDMA) based on the Free Space Optic (FSO) using Multi Diagonal (MD) code is. The proposed hybrid system is used to evaluate the contribution of different haze conditions of Malaysia as a tropical weather country as well as evaluating the effects of different noise types such as shot noise, thermal noise and Inter-Modulation distortion. This system has been evaluated numerically and by simulation analysis. The results of the simulation analysis that the proposed system can transmit 1 Gb/s for 2.5 km for heavy haze under the transmission power of 6dBm at BER 10-10.
