研究目的
To address the problem of noise accumulation in multi-cell networks under finite SNR conditions by presenting a user grouping scheme for reducing noise accumulation in a single cell and analyzing the impact of transmitter connections on the user grouping scheme.
研究成果
The paper concludes that the proposed SNR BIA mechanism significantly improves the achievable sum rate and is more robust to user mobility compared to other BIA mechanisms. The joint optimization of transmitter connections and user grouping scheme effectively reduces noise accumulation and enhances performance in multi-cell networks.
研究不足
The study is limited to the analysis and simulation of a two-cell network scenario. The practical implementation and scalability to larger networks with more cells and users are not explored.
