Abstract
In this paper, we simulate the performance of phase modulation in coherent Optical Code Division Multiple Access (OCDMA) systems. An Optical Spreading Sequences, a Prime Code family named Double Padded Modified Prime Code (DPMPC) sequence has been generated and employed because of its flexible code length. The number of active users to be interacted is made high by increasing the Code length value. In this analysis, BPSK format has been deployed where phase modulation has been done with optical signal and Convolutional encoding has been done to the modulated wave for real time error correction and at the receiver side decoding has to be done by using Viterbi algorithm to minimize the bit errors of the output by estimating the original input bits and demodulation of the decoded bits has also done. The Bit error rate analysis is also investigated for this network.
