Description: MIMO 表示多输入多输出。读/maimo/或/mimo/，通常美国人前者，英国人读后者，国际上研究这一领域的专家较多的都读读/maimo/。通常用于 IEEE 802.11n，但也可以用于其他 802.11 技术。MIMO 有时被称作空间多样，因为它使用多空间通道传送和接收数据。只有站点（移动设备）或接入点（AP）支持 MIMO 时才能部署 MIMO。-Multiple Input Multiple Output MIMO said. Read/maimo/or/mimo /, usually Americans former British reading the latter, international research expert in this field are more read/maimo /. Commonly used in IEEE 802.11n, but can also be used for other 802.11 technologies. MIMO spatial diversity is sometimes called, because it uses multiple spatial channels to send and receive data. Only site (mobile device) or access point (AP) support only when the deployment of MIMO MIMO. Platform: |

Description: To e ectively combat multipath fading across multiple protocol layers in wireless networks,
this dissertation develops energy-ecient algorithms that employ certain kinds of cooperation
among terminals, and illustrates how one might incorporate these algorithms into
various network architectures. In these techniques, sets of terminals relay signals for each
other to create a virtual antenna array, trading o the costs|in power, bandwidth, and
complexity|for the greater bene ts gained by exploiting spatial diversity in the channel.
By contrast, classical network architectures only employ point-to-point transmission and
thus forego these bene ts. Platform: |

Description: Transmit antenna selection(TAS) technology has been adopted for the uplink by the next generation Long Term Evolution wireless standard in order to harness the spatial diversity offered by multiple antennas at the mobile transmitter, while keeping the hardware complexity and cost of a mobile low. In TAS, the number of RF chains for processing/up-conversion is smaller than the number of available antenna elements, so at any time the signals can only be transmitted from a (dynamically optimized) subset of antenna elements. as a result, the training procedure for AS needs to be carefully engineered. In LTE, this is accomplished by reusing the wideband sounding reference signal for the purpose of AS training. Platform: |
