【Abstract】 The fundamental principles and system structure of fiber optical code division multiple-access(OCDMA) are introduced. The disadvantage and localization of binary system codes are analysed . The idea of using Multiphase Orthogonal Sequences to replace binary system sequences in OCDMA is given. The construction and capability of Multiphase Orthogonal Sequences are analysed and the idea that the use of Multiphase Orthogonal Sequences in OCDMA is a new way for research is given.更多还原
