Low power and long range machine-to-machine (M2M) communication techniques are
expected to provide ubiquitous connections for the wireless devices. In this paper, three …

Remarkable research activities and major advances have been occurred over the past
decade in multiuser multiple-input multiple-output (MU-MIMO) systems. Several …

Hybrid analog/digital precoding offers a compromise between hardware complexity and
system performance in millimeter wave (mmWave) systems. This type of precoding allows …

High directivity of 60 GHz links introduces new link training and adaptation challenges due
to both client and environmental mobility. In this paper, we design, implement and evaluate …

Passive indoor localization is important. Unlike active localization techniques, it does not
require for users to carry measuring devices, eg, smart phones. Thus, it is widely used in …

Numerous municipalities employ the smart city model in large cities to improve the quality of
life of their residents, utilize local resources efficiently, and save operating expenses. This …

In this letter, a four-element wideband multiple-input-multiple-output (MIMO) configuration
consisting of inverted L-monopole antenna (ILA) elements is proposed. An additional low …

Having been studied for more than a decade, Wi-Fi human sensing still faces a major
challenge in the presence of multiple persons, simply because the limited bandwidth of Wi …

Since the inception of IEEE 802.11 wireless local area networks (WLANs) in 1997, wireless
networking technologies have tremendously grown in the last few decades. The …

Information about the objects a person touches is an essential input to many applications in
ubiquitous computing. The ability to sense touch in the physical world can form the basis of …
