Optical code sequences for spectral-amplitude-coding optical CDMA systems

Abstract

OPTICAL SPECTRUM code-division multiple-access (OSCDMA) is a multiplexing technique adapted from successful implementation in wireless networks. In OSCDMA each user is assigned with a code sequence code that serves as an address. An optical CDMA user modulates its code / address with each data bit and initiates asynchronous transmission. This modifies its spectral appearance, recognizable only by the intended receiver and is a noise-like bursts for others.
