Sentence examples for multiple antennas which from inspiring English sources

Much research has emerged recently on MH relaying and multiple antennas, which means there are a large number of considerations in the design of such a system.

In[11], it is considered a similar scenario, but assuming that the nodes in the secondary network are provided with multiple antennas, which enables to considerably decrease the interference on the primary, without the need of global channel knowledge.

During the last decade, the cooperative communications have attracted lots of attention due to its ability to improve the system performance without the use of multiple antennas which increase the hardware complexity.

During the learning process of a cognitive MIMO radar system, the information of the environment, such as the prior knowledge of clutter and target impulse responses and noise, are collected by multiple receive antennas, which are transferred to multiple transmit antennas through a feedback mechanism for adjusting system parameters.

However, the method can easily be extended to scenarios with multiple transmit antennas, which is the normal mode of dedicated pilots and beamforming.

Although we only discuss the simplest uplink scenario--two transmit antennas and one receive antenna, it can be easily extended to more general MIMO systems with multiple receive antennas, which can increase the spatial diversity gain.

More importantly, motivated by this geometrical interpretation we show that such a loss can be mitigated by exploiting multi-user diversity and spatial diversity in the multi-user system with multiple receive antennas, which is usually available in mobile systems nowadays.

The mobile user equipments (UEs) have multiple antenna elements which allow maximal ratio combining of the received signals.

The authors in [15] propose a mitigating interference using multiple antennas (MIMA) protocol which uses a cross-layer design between MAC layer and physical layer [16] to reduce interference and improve network throughput.

The MIMO structure in the diagram is the simplest case of two transmitting antennas and two receiving antennas, which can be extended to multiple receiver antennas with increased spatial diversity gain.

There are now cellphones with metamaterial antennas, which are smaller than conventional ones and can better handle multiple frequencies.
