OCDMA NETWORK ARCHITECTURES, OPTICAL CODERS AND METHODS FOR OPTICAL CODING

摘要

The present invention relates to a kind of OCDMA network architecture. It encodes for the frequency hopping for obtaining a tiny bit valuableness for a large number of users, the network includes: passband filtering and the Duplex-Wideband signal of multiple tools (81), and each described device (81) is assigned each group that the broadband signal of one group of user (80) and filter is provided by user (80) group filtered with different passbands with users multiplexing (80); Periodical light code coder (82) distributes to multiplexing of the every group of user (80) for encoded signal by device (81) for filtering and being multiplexed, and each encoder (82) is using the signal of different code codings derived from difference; With input unit (83), for combine the signal exported by encoder (82) to single broadband signal. Present invention is equally related to further framework, encoder appropriate and corresponding method.
