In views of optical CDMA confidentiality, this paper proposes a signature reconfiguration scheme over the OCDMA network coder/decoders (codecs) design. By exclusively assigning to each network user a set of pseudo-orthogonal M-sequence signature codes and selecting one among them to represent each user's signature. A central node station is assumed to monitor network traffic condition and to signal...
In views of reconfiguring optical CDMA (OCDMA) network coder/decoders (codecs), a dynamic signature coding scheme structured over arrayed-waveguide gratings (AWGs) is devised. The signature reconfiguration can find applications on enhancing OCDMA network confidentiality. On the basis of cyclic and periodic characteristics of M-sequence codes compatible with free-spectral range (FSR) of novel prime-dimension...
In views of optical CDMA confidentiality, this paper proposes a signature reconfiguration scheme over the network coder/decoders (codecs) design. By exclusively assigning to each network user a set of pseudo-orthogonal M-signature codes and randomly selecting one among them to represent each user's signature. A central node station is assumed to monitor network traffic condition and to signal transceiver...
Dynamic signature reconfiguration is proposed to combat with eavesdroppers to enhance confidentiality over multi-rate optical code-division multiple-access (OCDMA) networks. The code reconfiguration is achieved by exclusively assigning to each network user a set of orthogonal or pseudo-orthogonal codes and randomly selecting one among them to represent each user's signature. A central node station...
