Abstract

We propose an effective method for a secured Orthogonal Wavelet Division Multiplexing (OWDM) communication facilitated using various randomly generated sequences like Gold codes, Kasami sequences undergoing Haar wavelet transform. A random sequence is considered, where predictability of each term is negligible to the uninitiated and the digits satisfy particular number of tests according to the predefined conditions of the user along the transceiver. The efficient form of modulation used for OHWDM systems when it comes to improving security at the most abstract level of communication is found. Security level of the system is improved by using fractals as inputs and replacing Fourier by wavelet transform, which leads to OHWDM. Efficiency of the system is improved and is shown by the time taken by the transceiver.
