diversity antenna

Then the mutual coupling between BS diversity antennas are described in detail forthe horizontal spaced diversity antenna system.

对水平空间分集天线系统中基站天线之间的相互耦合影响进行了详细地讨论。

Space or multi-antenna diversity techniques are particularly attractive as they can be readily combined with other forms of diversity, e.g., time and frequency diversity, and still offer dramatic performance gains under these bases.

空间或多天线分集技术由于可以与其它如时间分集，频率分集技术相结合，并在其基础上提供很大的性能增益，而成为一种很有吸引力的技术。

Therefore, cooperative diversity has been proposed, which enables single-antenna users to exploit space diversity in a distributed way by sharing their antenna and creating the virtual antenna array ( VAA) for relayed transmission.

合作分集技术是利用其他用户的天线构成虚拟天线阵（VAA），中继传输信息，从而实现分布式空间分集。

Space time coding is a channel coding scheme for MIMO system, which combines the merits of the spatial-diversity and time-diversity. It provides both diversity gain and coding gain, which can provide much higher data rate-to-bandwidth ratio than single-antenna system.

空时编码是适合于多天线阵信道的一种编码方案，它综合了空间分集和时间分集的优点，同时提供分集增益和编码增益，能够获得远远高于传统单天线系统的频谱利用率。

MIMO technology combined with antenna diversity and space-time processing technology, which originated from antenna diversity and smart antenna technology can be said to belong to a broad scope of the smart antenna.

MMO技术结合了天线分集与空时处理技术，它源于天线分集与智能天线技术，可以说属于广义的智能天线范畴。
