Manchester Signaling Scheme for Enhanced Ground to Satellite DWDM Communication with 32 Channel Modulation and Optical Amplification

Problem Definition

The reference problem defining the drawbacks of the RZ modulation technique highlights several key limitations and pain points within the specified domain. One of the major issues is the presence of the DC level, which can lead to signal degradation and hinder system performance. Additionally, the continuous non-zero component at 0 Hz, known as "Signal Droop," poses challenges in signal transmission and can affect the overall quality of the system. Moreover, the lack of error correction capability in RZ modulation further exacerbates potential errors and limits the system's robustness. These inherent drawbacks make RZ modulation non-transparent and ultimately compromise the efficiency and effectiveness of the system.

Addressing these issues is vital in improving the performance and reliability of the system, highlighting the necessity of developing alternative modulation techniques that can overcome these limitations.

Objective

The objective of this work is to address the drawbacks of RZ modulation in communication systems by proposing the use of Manchester encoding instead. By implementing Manchester encoding, the goal is to eliminate the DC level, signal droop, lack of error correction capability, and lack of transparency associated with RZ modulation. The proposed Dense Wavelength Division Multiplexing (DWDM) communication system is specifically tailored for clear weather conditions and turbulence-induced channels. Additionally, the work aims to expand the number of channels from 16 to 32 to meet increasing user demands, ultimately improving system performance and reliability.

Proposed Work

Input Data: The problem definition of using RZ modulation in communication systems is that it comes with various drawbacks, such as the presence of the DC level, signal droop at 0 Hz, lack of error correction capability, and lack of transparency. These drawbacks ultimately lead to degraded system performance. To overcome these issues, a Dense Wavelength Division Multiplexing (DWDM) communication system is proposed specifically designed for clear weather conditions and turbulence-induced channels. The objective is to implement Manchester encoding to replace RZ encoding and improve system performance. The proposed work involves using Manchester encoding instead of RZ modulation due to its numerous advantages.

Manchester coding eliminates the DC component by assigning positive and negative voltage contributions to each bit, it does not suffer from signal droop, it has error detection capabilities, and it provides a transition for every bit in the middle of the bit cell for synchronization. These advantages of Manchester encoding address the issues caused by RZ modulation, leading to enhanced system performance. Furthermore, while previous work only considered modulation for 16 channels, the proposed work expands this to 32 channels to meet the increasing user demand. By adopting Manchester encoding and increasing the number of channels, the proposed approach aims to overcome the drawbacks of RZ modulation and achieve an efficient communication system.

In the telecommunications sector, the elimination of the DC level and signal droop, along with the error detection capability of Manchester encoding, can improve the performance of communication systems. In data communication and networking, the transparent nature of Manchester encoding and its synchronization capabilities make it a suitable choice for efficient data transmission. The increase in the number of channels from 16 to 32 in the proposed work also caters to the growing demand for higher data capacity in industries, ensuring the scalability of the system to meet industry requirements. Overall, the benefits of implementing Manchester encoding in industries include enhanced system performance, improved data transmission efficiency, and adaptability to increasing demand for data capacity.
