摘要
未来无线通信系统需要更高的数据传输速率和更好的服务质量,因此需要系统容量大幅度提高。在有限的无线频谱资源条件下,只有极大地提高频谱利用率才能使系统容量更高。采用多输入多输出(MIMO)天线技术可以满足要求。MIMO技术的主要研究方向包括:MIMO信道、MIMO收发技术、分布式MIMO和MIMO应用。MIMO技术是无线通信领域重大的技术突破,将成为未来无线宽带移动通信系统和无线宽带接入系统的关键技术。
The future wireless communications system requires higher data transmission speed and better QoS, therefore the system capacity should be greatly improved. With limited radio frequency resources, it can only be satisfied by tremendously enhancing the frequency utilization efficiency. The Multiple Input Multiple Output (MIMO) technology is a good choice. The study of MIMO includes MIMO channel, MIMO transceiver, distributed MIMO and application of MIMO. The MIMO technology is a great technological breakthrough in the domain of wireless communications, and it will become a key technology for the future broadband mobile communications system and broadband wireless access system.
