Abstract :
A new code design algorithm for application in three-dimensional (3-D) optical code division multiple access (OCDMA) for asynchronous optical fiber communication is proposed. In this paper, 3-D refers to space-wavelength-time spreading. The performance analysis of the proposed algorithm in 3-D multiple pulses per plane codes is shown. This design ensures a maximum cross-correlation of 1 between any two codes. The performance metrics that have been investigated are bit error rate due to multiple access interference for varying number of simultaneous users and, cardinality for different values of temporal length.
