A new two-dimensional (2-D) optical code division multiple access (OCDMA) scheme to increase the achievable system capacity is proposed. The code exhibits good cross-correlation property time and wavelength shift. Performances are analyzed on code size and correlation properties affecting two important system parameters, bit error rate (BER) as a function of cardinality generated and optical power...
We apply the arrayed waveguide grating (AWGs) method for encoder and decoder design for complete transmitter and receiver system. The encoder and decoder module will be using the AWG to encode and to decode optical source into useful signal to carry the data and transmit it using a single optical fibre. This module was designed to suite the zero cross correlation (ZCC) code. In this paper the study...
A new code of optical code division multiple access (OCDMA) namely optical zero cross correlation (ZCC) is proposed in this paper. The code construction design is flexible since the number of user and weight can easily be increased using mapping and transformation method respectively .The performance of the system with the proposed code is simulated and analyzed using Optisys 5.0 in comparison the...
