Spectral amplitude coding OCDMA using AND subtraction technique

Abstract

A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and the calculated and simulation results have been done by comparing AND subtraction technique against Complementary subtraction technique by using DW code. In this paper we have proved that AND subtraction technique gives better Bit Error Rate (BER) performance than Complementary subtraction technique.
