中文摘要：
如何在多小区环境更好地利用MIMO技术，抑制或降低小区间干扰是关键，但是，仅通过单个基站处理无法解决小区间干扰问题。系统总结并探讨了抑制MIMO蜂窝系统中小区间干扰的多基站联合处理算法研究进展，包括MIMO系统中降低小区间干扰的方案总结、多基站联合处理模型、多基站联合处理算法分析、存在问题和研究展望等。这对多小区传输技术的进一步研究具有重要作用，对MIMO技术的实用化具有重要价值，对发展新一代移动通信技术具有重要意义。
英文摘要：
How to make a better use of MIMO technology to restrain and reduce the interference under the environment of multi-cell is the key. However, the problem of inter-cell interference （ICI） cannot be solved only by single base station. This paper summarizes the advances in studies of muhi-BS joint processing algorithms for inter-cell interference mitigation in MIMO cellular systems, including the summarization of the scheme for reducing the ICI in MIMO system, the muhi-BS joint processing model, the muhi-BS joint processing algorithm and its problems, the research perspective, and so on. It is of significance for the further study of multi-cell transmission technology, the practice implementation of MIMO technology, and the development of new generation mobile communications.
