The proposal of high capacity GHZ soliton carrier signals applied for wireless communication

Abstract

Nonlinear behavior of light inside the microring resonator (MRR) show very interesting phenomena where the high capacity ranges can be obtained for long distance communication. Optical soliton is a self-reinforcing solitary wave that maintains its shape while it travels at constant speed. MRR can be an interesting tool to generate solitonic pulses needed in wireless communication systems. To make the proposed systems with practical device, the suitable parameters are used to adjust and provide the output results. Wireless networks have some advantage comparing with wire networks such as the cabling is not required and mobility services. OFDM is a widely used modulation and multiplexing technology which has become the basis of many telecommunications standards for both wired and wireless communication networks. The basic principle of OFDM is to split a high-rate data stream into a number of lower rate streams that are transmitted simultaneously over a number of subcarriers. In this proposal we discuss the generating of carrier signals using soliton pulses for OFDM modulation. The mathematical equation of the ring system is solved using the Z-transform method, where the simulation of the result is handled by coding the equations using the MATLAB software licensed by the Universiti Teknologi Malaysia (UTM).
