This paper presents a multiple frequency bands-switching scheme for wideband channel
sounding, which is able to extend the overall sounding bandwidth without changing …

In massive multiple-input multiple-output (MIMO) systems, the favorable propagation which
can be also known as the orthogonality of the channel between different users is the most …

In this paper, we use the multipolarized antennas in massive multiple‐input multiple‐output
(MIMO) systems to decline the channel orthogonality and enhance the system performance …

This paper experimentally verifies the potential of higher order space division multiplexing in
line-of-sight (LOS) channels for multiuser massive MIMO. We previously proposed an inter …

In this paper, a novel design of a Uniform Circular Array Massive-Multiple Input Multiple
Output (UCA-mMIMO) system based on Spherical Wave (SW) is proposed in Uplink (UL) …

Massive MIMO (multiple‐input multiple‐output) is a fundamental technology in 5G systems.
The characteristics of the radio channel experienced when operating with large antenna …
