Abstract

Tropical regions are characterized by intense and persistent rainfall throughout most of the year, and this environmental condition significantly influences wireless communication performance. The continuous presence of heavy precipitation weakens, scatters, and disrupts radio frequency signals, causing noticeable attenuation during transmission from the source to the destination. As a result, reliable communication becomes challenging, particularly for modern high-speed systems such as 5G networks. To address this limitation and enhance communication quality in such climates, this research proposes a robust design for a 5G communication link specifically tailored for areas that experience frequent rainfall. In the proposed model, three independent frequency-selective Rayleigh fading channels are configured to realistically represent the propagation environment in tropical regions. To further improve the reliability and data throughput of these channels, convolutional coding schemes with code rates of 1/3 and 3/4 are incorporated. Additionally, multiple digital modulation techniques—namely 8PSK, 16PSK, 32PSK, 64PSK, and 16QAM—are implemented to analyze their influence on signal capacity, data security, and bandwidth efficiency. Comprehensive comparative evaluations of these modulation schemes across different code rates and Rayleigh channels are carried out to determine which combination yields the lowest bit error rate (BER). The results highlight the modulation approaches most capable of maintaining effective communication in heavy-rainfall environments, providing valuable insights for future 5G link designs optimized for tropical climates.
