There is considerable pressure to define the key requirements of 5G, develop 5G standards,
and perform technology trials as quickly as possible. Normally, these activities are best done …

The field of wireless communication networks has witnessed a dramatic change over the last
decade due to sophisticated technologies deployed to satisfy various demands peculiar to …

This paper proposes a non-stationary three-dimensional (3D) irregular-shaped geometry-
based stochastic model (IS-GBSM) for fifth generation (5G) and beyond massive multiple …

This paper proposes a novel theoretical non-stationary three dimensional (3-D) wideband
twin-cluster channel model for massive multiple-input multiple-output (MIMO) …

This paper proposes a novel non-stationary wideband multi-confocal ellipse two
dimensional (2-D) channel model for massive multiple-input multiple-output (MIMO) …

Cluster-based channel modeling has been an important trend in the development of
channel model, as it maintains accuracy while reducing complexity. Whereas a large …

In this paper, a general three-dimensional (3D) space-time-frequency non-stationary model
is proposed for sixth generation (6G) channels. From the proposed model, a novel method …

Propagation models constitute a fundamental building block of wireless communications
research. Before we build and operate real systems, we must understand the science of …

As new systems and applications are introduced for next-generation wireless systems, the
propagation channels in which they operate need to be characterized. This paper discusses …
