MIMO increases receiver signal-capturing power by enabling antennas to combine data streams arriving from different paths and at different times. Smart antennas use spatial diversity technology, which puts surplus antennas to good use. When antennas outnumber spatial streams, the antennas can add receiv...
多入多出(MIMO,Multiple-Input Multiple-Out-put)技术,就是指无线网络信号通过多重天线进行同步收发,MIMO系统在发射端和接收端均采用多天线(或阵列天线)和多通道,从而提高传输率。该技术能在不增加宝贵频宽的基础上成倍地提高通信系统的容量和频谱利用率。《MIMO技术浅谈 》°MIMO技术浅谈 ¡查看...

This dissertation studies a number of important issues that arise in multiple-input multiple-out wireless systems. First, wireless systems equipped with multiple-transmit multiple-receive antennas are considered where an energy-based antenna selection is performed at the receiver. Three different ...

The antenna also comprises a metal component disposed in the air between or outside of the said two adjacent antennas, and said metal component functions as a reflector or a director of said antennas. The present invention also discloses a mobile terminal. With the MIMO antenna and mobile ...
Find out how MIMO (multiple input, multiple output) uses multiple antennas at both the source (transmitter) and the destination (receiver) to enhance wireless communications. MIMO technology creates a more stable connection and less congestion.
UEs 120 may be dispersed throughout the system, and each UE may be stationary or mobile. A UE may also be referred to as a mobile station, a terminal, an access terminal, a subscriber unit, a station, etc. A UE may be a cellular phone, a personal digital assistant (PDA), a ...
仔细看了一下 Hadoop.MapReduce 的代码,发现了两个新类:MultipleInputs/MultipleOutpus,再仔细看它们的详细文档,的确实现了我想要的功能: 不同的InputPath,可是使用不同的InputFormat 和 Mapper 可以将不同类型(可能是多种计算)的结果写入不同的Reduce Output。
Millimeter-wave (mmWave) multiple-input multiple-out (MIMO) systems relying on lens antenna arrays are capable of achieving a high antenna-gain at a considerably reduced number of radio frequency (RF) chains via beam selection. However, ... W Shen,X Bu,X Gao,... 被引量: 0发表: 2020年...
