Abstract :
The wireless systems in Malaysia are influenced by turbulent weather which leads to a large signal fading or attenuation. This paper proposes using the hybrid Subcarrier Multiplying (SCM)-Spectral Amplitude Coding (SAC) Optical Code Division Multiple Access (OCDMA) system based on Multi-Diagonal (MD) code using Free Space Optic (FSO). The study has found out that the hybrid system can be used in the mesh network. The proposed hybrid technique has been analyzed by taking into account the effects of the haze and rain attenuations. Furthermore, we have described modulation scheme, atmospheric effects, data security, the FSO mesh network and simulation. The above method produces less Bit-Error Rate (BER) at storm rain and at heavy haze.
