Simulation of optical CDMA system based on bipolar code

الملخص EN

A unique attribute of optical CDMA is the use of optical processing, which can circumvent electronics bottlenecks and which potentially can implement directly in the optical domain certain network operations, such as addressing and security, which traditionally have been performed electronically.

There has been a recent upsurge of interest in applying Code Division Multiple Access (CDMA) techniques to optical networks.

In this paper proposed and simulate a technique to generate bipolar encoder for multiple access communications systems like UWB bipolar code that experimentally proposed .This technique based on electro-optic phase modulation and phase to intensity modulation conversion depend on fiber Bragg grating .

a bipolar code are generated with code length of 4 was achieved.
