Modified Duobinary RZ Modulation OWC for Bengaluru Weather Conditions

In optical wireless communication (OWC), adverseweather conditions such as heavy rainfall in regions like Bengaluru can severely impact signal quality and transmission reliability. This paper proposes the design and evaluation of a Modified Duobinary RZ (Return-to-Zero) modulation scheme tailored specifically for mitigating these effects in Bengaluru's weather conditions. The study aims to enhance the robustness of OWC systems by leveraging the unique characteristics of Duobinary RZ modulation, which offers improved spectral efficiency and noise resilience compared to conventional modulation techniques. Through simulations and possibly experimental validations, the design will assess the performance of the proposed scheme under varying atmospheric conditions, considering factors like attenuation, Q factor, and bit error rate (BER). The outcomes are expected to contribute valuable insights into enhancing the reliability and performance of OWC systems operating in challenging weather conditions, particularly in urban environments like Bengaluru.
