Abstract

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 pseudoorthogonal 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 transceiver coder-decoder pair to perform signature codes changing. We structure the detailed M-signature codecs design over arrayed-waveguide grating devices. We also use the successive interference cancellation (SIC) technique to enhance the system performance.

Keywords: signatures reconfiguration;optical code-division multiple-access (ocdma);arrayed-waveguide grating (awg);free spectral range (fsr);balanced photo-detector (bpd)
