在HSPA+中，主要用到的就是MIMO技术，请问这个技术具体的含义和概念是什么？

说到具体，建议楼主最好找一些相关的书籍看看，论坛里有的。

多进多出技术，是关于天线的

我听过一次我们内部培训 好像大概实施起来就是小天线密集覆盖 比较适合高端居民社区 我们在新疆“鬼城”有一个试验站点

多天线小区，提升容量用的。
时间:  2012-1-29 13:19
作者: ruibin198928

<strong>多入多出(MIMO)或多发多收天线(MTMRA)技术是无线移动通信领域智能天线技术的重大突破。该技术能在不增加带宽的情况下成倍地提高通信系统的容量和频谱利用率，是新一代移动通信系统必须采用的关键技术。 </strong>

<strong>一句话，MIMO（Multiple-Input Multiple-Out-put）系统就是利用多天线来抑制信道衰落。根据收发两端天线数量，相对于普通的SISO（Single-Input Single-Output）系统，MIMO还可以包括SIMO（Single-Input Multi-ple-Output）系统和MISO（Multiple-Input Single-Output）系统。 </strong>
