Manchester Signaling Scheme for Ground to Satellite DWDM Communication

Abstract

For the modulation of various data streams, Wavelength division multiplexing is utilized. Further, Dense Wavelength Division multiplexing is the type of WDM which is capable of spacing the wavelengths more closely due to its greater capacity. This technology is widely used in fiber optics as it utilizes the bandwidth in an appropriate manner. Various researchers have been carried out to make it worth using. Recently, in research, the author had used DWDM in clear weather conditions and turbulence generated in a channel. In this work, the author had utilized the RZ modulation technique which has some drawbacks. Due to this, the performance of the entire model is affected. Thus in this paper, a novel approach is presented to overcome the problems of the existing system. In the novel system, RZ encoding is replaced by Manchester encoding. Manchester encoding has several advantages over RZ encoding. Further, the simulation of the model is performed under the opti-system. Here, the Q-factor of both (proposed and with RZ encoding) models are determined in terms of a single channel, 4 channels, and 16 channels. The results showed the effectiveness of the proposed system as it increases the quality of the signal transmitted from one source to another.
