ABSTRACT

This study explores the impact of elevation angle on Cross Polarization Discrimination (XPD) in telecommunication systems,as evidenced by data collected under varying rain conditions. The study examines XPD values at elevation angles of 400 and 600 degrees across different rain classifications and intensities. Analysis of the data reveals that increasing the elevation angle generally leads to improvements in XPD, indicating enhanced discrimination against cross-polarized interference and improved signal quality. Notably, significant improvements in XPD are observed in conditions of widespread rain at higher elevation angles. However, the effectiveness of elevating antennas in mitigating interference diminishes as rain intensity increases, particularly in extreme cloudburst scenarios. The findings underscore the importance of considering elevation angle in antenna placement and system design to optimize XPD and ensure reliable communication performance, especially in adverse weather conditions. This research contributes to a deeper understanding of the complex relationship between elevation angle and XPD, offering valuable insights for the design and optimization of telecommunication networks.
