Hybrid Transmitter Design: Enhancing Signal Modulation with Channel Diversity, CSRZ, and DQPSK

Problem Definition

The existing literature on inter-satellite optical wireless communication (IS-OWC) systems highlights several key limitations and challenges that need to be addressed. One major drawback is the impact of various quality factors, such as varying wavelengths and types of detectors, on the performance of the communication network. These factors have been observed to have an adverse effect on data transmission rates and signal strength, ultimately degrading the overall performance of the IS-OWC systems. Additionally, factors like aiming errors, vibration errors, misalignments, tracking issues, and noise further contribute to the deterioration of system quality. Traditional models of IS-OWC systems have failed to consider these crucial quality factors, focusing instead on the overall system quality without addressing the specific issues that can lead to reduced data transmission rates and signal strength.

As a result, the functioning of IS-OWC systems has been compromised, leading to decreased performance and reliability. In order to overcome these limitations and enhance the quality and signal strength of IS-OWC systems, a new model has been proposed that aims to address these key issues and improve the overall performance of inter-satellite communication networks.

The objective of this study is to address the limitations and challenges faced by traditional Inter-Satellite Optical Wireless Communication (OWC) systems by introducing a new model. This model aims to enhance signal strength at the receiving end with minimal Bit Error Rate (BER) and pointing errors by using a hybrid transmitter and implementing a diversity channel technique. The proposed model also includes advanced components at the receiver end to efficiently detect and analyze input signals. By combining these innovative techniques and components, the goal is to improve the overall quality and signal strength of inter-satellite communication networks, ultimately leading to enhanced communication efficiency and reliability.

Proposed Work

In this proposed work, the focus is on addressing the limitations of traditional Inter-Satellite Optical Wireless Communication (OWC) systems by enhancing the signal strength at the receiving end with minimal Bit Error Rate (BER) and pointing errors. This is achieved by introducing a hybrid transmitter using CSRZ-DQPSK modulation technique for signal modulation. Additionally, a diversity channel technique is implemented to mitigate the impact of various factors such as misalignment, vibration errors, and tracking issues. By transmitting signals on multiple correlated channels, the effects of fading are minimized, leading to improved system performance. Furthermore, the proposed model includes the use of advanced components at the receiver end such as an avalanche photodetector (APD), low pass Bessel filter, 3R regenerator, and a BER analyzer to efficiently detect and analyze the input signals.

By combining these innovative techniques and components, the goal is to enhance the overall quality and signal strength of the inter-satellite communication network. The rationale behind choosing these specific techniques and algorithms lies in their ability to address the identified issues in traditional systems and improve the performance of the system as a whole. Through this proposed work, it is expected to achieve enhanced communication efficiency and reliability in Inter-Satellite Optical Wireless Communication systems.
