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/Ro ff and generates I/I0 in a non linear fashion

Abstract: The Mutation plays a very important role in the process of object (image) detection and its extraction. It has been considered in the form of matrices so that it can identify a space which is like that of a Euclidean-space. The covariance features' performance is superior and quicker than most of the procedure usually followed. This paper presents a new method for human face recognition by utilizing Mutation. Here Mutation based on region covariance matrices is used to simulate the effects of errors that happen with low probability during duplication. Both pixels locations and Mutation coefficients are employed to form the covariance matrices. Experimental outcomes reveal the advantages of this proposed method.
