 The rapid development of wireless communication technology has led to increasingly spectrum resources, with interference emerging as a key factor constraining the performance enhancement of wireless networks. To address this issue, this study focuses on interference coordination and performance optimization in wireless networks, aiming to improve system capacity and user experience through effective interference management strategies. Grounded in modern communication theory, the research integrates optimization algorithms and simulation analysis methods to propose a novel distributed interference coordination mechanism. This mechanism introduces intelligent resource allocation strategies that significantly enhance spectrum utilization while ensuring fairness. Furthermore, targeting the complex interference environments in heterogeneous network scenarios, an adaptive interference suppression algorithm is designed, capable of dynamically adjusting parameters to accommodate varying network load conditions. Experimental results demonstrate that the proposed scheme exhibits superior performance in reducing interference levels, improving link quality, and enhancing network throughput, achieving over 30% performance improvement compared to traditional methods. Additionally, this study explores the potential application of machine learning techniques in interference coordination, validating their effectiveness in predicting interference patterns and optimizing resource allocation. Overall, the research outcomes not only provide new insights into interference management in wireless networks but also lay a theoretical foundation for the design and deployment of future high-density networks, holding significant academic value and practical implications.
