摘要由于多天线系统在空间资源利用方面的独特优势，多天线系统已成为无线通信研究的热门场所十多年。 MIMO 技术是新一代 IMT-Advanced 标准移动通信系统的基本物理层技术之一，因为许多天线可以在有限的时频资源下实现更高的通信速度和可靠性现在是。 MIMO 系统中的预编码和用户规划技术是近年来发展最快的领域。从理论研究到行业标准，重点是针对多个用户的单细胞系统的单细胞系统，以及用户系统中的尺寸预编码和用户规划技术。在本文中，如何为许多用户规划基站在下游 MIMO 系统之间连接的使用，特别是如果发射机对每个用户的信道条件有限的信息特别是你使用上校的父母分析，信息理论和信号处理理论吗？合理设计每个用户的预编码和其他测试问题。本研究的目的是减少不同用户之间的信道间干扰，减少不同小区之间的小区间干扰，并最大化每个用户的等效信道增强。通过合理的通信机制和优化的信号设计和复杂性来提高系统级别指标，如系统和容量，故障率，现有无线通信技术标准的几个因素 3 GPP LTE 同样。关键词：多输入多输出，预编码，用户调度，有限反馈，多点协同Abstract: Due to the unique advantages of multi-antenna systems in the use of space resources, multi-antenna systems have become a hot spot for wireless communication research for more than a decade. MIMO technology is one of the basic physical layer technologies of the new generation of IMT-Advanced standard mobile communication systems, because many antennas can achieve higher communication speed and reliability under limited time-frequency resources. Precoding and user planning techniques in MIMO systems are the fastest growing areas in recent years. From theoretical research to industry standards, the focus is on single-cell systems for single-cell systems for multiple users, as well as size precoding and user planning techniques in user systems.In this paper, how to plan the use of base station connections between downstream MIMO systems for many users, especially if the transmitter has limited channel conditions for each user, e...
