Abstract

Multiple accesses which uses the spread spectrum technology for transmission has become very popular in cellular radio networks. In this thesis, a highly spectral-efficient transmission technique based on optical code division multiplexing (OCDM) is investigated. Optical transmission systems have to meet the rapid increase in the demand of data bandwidth and spectral efficiency. OCDM provides asynchronous transmission, secure communication, soft capacity on demand, and high degree of scalability. In this paper, we have applied OCDM technique along with fuzzy logic generator which gives us improvement .Fuzzy Logic generator accepts Vπ and Ron/R off and generates I/I0 in a non linear fashion.
