A New Design of Code for Optical Network for Security Enhancement

Utkarsh Agrawal; Sumit Gupta

This paper proposes a new method to develop the new code for optical network which uses the Double weight (DW) Code in bipolar mode with an improved ideal in phase cross correlation property at the receiver end. An Encoder is constructed in such way that the power of the cross - correlation pulse of a user is kept constant when another user is transmitting ‘0’ information bit while code assigned to both users is ideal in phase cross correlation. The chip position at the Cross correlation is switched in code to eliminate the continuous presence of a cross correlation spectral chip at the transmitter and receiver end when users in basic code transmit‘0’information bit. Mathematical and simulation analysis is carried out and the result shows the better performance than the existing code like RD and MQC codes.
