Wireless communication systems continually strive for improved performance in the presence of fading channels. This study focuses on optimizing wireless communication through the performance analysis of Space-Time Trellis Codes (STTC) in Nakagami fading channels. STTCs have emerged as powerful tools to mitigate the adverse effects of fading channels, and this research investigates their performance characteristics in Nakagami fading environments. Through comprehensive analysis and simulations, the study aims to provide valuable insights into the design and deployment of STTCs to enhance the reliability and efficiency of wireless communication systems.
