Emerging Optical CDMA Techniques and Applications

Encoding Techniques in Optical Cdma

The demand for higher data rates along with variable QOS and variable bandwidths has led to the remarkable advancements in the communication technology. To meet the above-listed objectives, whereas the TDMA and WDMA require complex protocols and extensive hardware, the CDMA systems are much simpler and very easily support the above-mentioned services. Since optical CDMA systems assigns unique c...

Optical CDMA Networks Using Different Detection Techniques and Coding Schemes

This paper presents the comparative performance of different detection and coding schemes for spectral-amplitude-coded optical code division multiple access (SACOCDMA) system. SAC-OCDMA systems are receiving more attention because of their ability to completely eliminate multiple access interference (MAI). Fiber Bragg grating (FBGs) are used as encoder/decoder. Experimental simulation was carri...
