Multiple-input multiple-output (MIMO) technology is maturing and is being incorporated into
emerging wireless broadband standards like long-term evolution (LTE)[1]. For example, the …

We consider the uplink (UL) and downlink (DL) of non-cooperative multi-cellular time-
division duplexing (TDD) systems, assuming that the number N of antennas per base station …

We consider a multicell MIMO uplink channel where each base station (BS) is equipped with
a large number of antennas N. The BSs are assumed to estimate their channels based on …

In this paper, we perform transmit antenna selection to improve the energy efficiency of large
scale multiple antenna systems. We derive a good approximation of the distribution of the …

In recent years, a wealth of research has emerged addressing various aspects of mobile
communications signal processing. New applications and services are continually arising …

As a prospective key technology for the next-generation wireless communications,
reconfigurable intelligent surfaces (RISs) have gained tremendous research interest in both …

This paper concerns the uplink of multicell multiuser multiple-input multiple-output (MIMO)
systems. To tackle the effect of pilot contamination that is generally viewed as a bottleneck in …

A complete multiple-input multiple-output (MIMO) system model with compact arrays at both
link ends containing arbitrary matching networks is presented based on a Z-parameter …

The electromagnetic (EM) degrees of freedom (DOF) of a noise limited system in two
dimensions with random multiple scattering is evaluated numerically following a rigorous …

In this paper, we analyze the performance of novel wearable multiple-input-multiple-output
(MIMO) systems, which consist of multiple electrotextile wearable antennas distributed at …
