Abstract
With the rapid development of modern communication technology, signal processing, as a core component of communication systems, directly affects the stability and efficiency of the system. This study focuses on the application of filter-based signal processing techniques in communication systems, aiming to enhance signal transmission quality and interference resistance through optimized filter design. By integrating theoretical analysis with simulation validation, this research thoroughly investigates the performance of different filter types, such as FIR and IIR filters, in channel equalization, noise suppression, and spectrum management, and proposes an adaptive filtering algorithm to address signal processing requirements in complex dynamic environments. Experimental results demonstrate that the proposed algorithm exhibits significant advantages in reducing bit error rates and improving spectrum utilization, achieving approximately 20% better performance compared to traditional methods. Furthermore, this study innovatively incorporates machine learning techniques into the optimization of filter parameters, thereby enhancing the system's adaptability and robustness. Overall, this research provides new insights into the design and application of filters in communication systems and plays a crucial role in advancing the development of efficient and reliable next-generation communication technologies.
