They allow not only the integration of a microchip but also of a sensor commonly used in the agricultural field such as a global navigation satellite system (GNSS) receivers and a variety of sensors . The present use model of high-speed networks for email and multimedia content, together with...
The main backbones behind these evolutions are technological developments in the underlying mobile radio technology such as multicarrier technology (majorly OFDMA), multiple-antenna technology (MIMO) and the application of packetswitching to the radio-interface through improvements in techniques like ...
As multi-antenna without phase-controlling being used in MIMO system to transmit signals with the same carrier frequency, directional transmission beam would be produced in MIMO system, which would form a number of blind spots of radio coverage. The ...
This paper was aimed at discussing the feasibility of using MIMO in high-speed railway communication and incurring potential performance gain. Through the help of the simulate platform of MATLAB-SIMULINK, a model of multi-antenna communication system with the maximum speed of 300km/h was constructed...
This paper proposes a practical application of Massive MIMO technology, Massive Antenna Systems for Wireless Entrance (MAS-WE), and its related inter-user interference (IUI) cancellation and scheduling techniques. MAS-WE, on which the entrance base station (EBS) employs a large number of antennas...
An antenna structure for MIMO application includes a substrate, a first antenna element, and a second antenna element. A metal ground layer covers a portion of a first surface of the substrate, and th
In this paper we propose a novel reconfigurable antenna that may be used as elements of a MIMO system to improve the capacity. Reconfiguration is achieved by switching in various parts of the antenna into the current path. For switching PIN diodes may be used. The antenna can give polarization...

A dual-band multiple-input-multiple-output (MIMO) antenna covering 2.2–2.7GHz and 4.9–5.9 GHz frequency bands for wireless local area network (WLAN) application is presented. The proposed antenna consists of two C-shaped monopole antenna elements and a decoupling structure. The decoupling structur...
Beamforming and Multiple Input Multiple Output (MIMO) have been identified as key technologies to meet the ever increasing capacity demands in future mobile cellular networks. So far, these features have mainly been investigated in the azimuth dimension, considering one-dimensional antenna arrays. Recen...
