As a paradigm to recover the sparse signal from a small set of linear measurements,
compressed sensing (CS) has stimulated a great deal of interest in recent years. In order to …

With the development of intelligent networks such as the Internet of Things, network scales
are becoming increasingly larger, and network environments increasingly complex, which …

Massive access, also known as massive connectivity or massive machine-type
communication (mMTC), is one of the main use cases of the fifth-generation (5G) and …

Hybrid analog and digital precoding allows millimeter wave (mmWave) systems to achieve
both array and multiplexing gain. The design of the hybrid precoders and combiners …

Antenna arrays have a long history of more than 100 years and have evolved closely with
the development of electronic and information technologies, playing an indispensable role …

With the large number of antennas and subcarriers the overhead due to pilot transmission
for channel estimation can be prohibitive in wideband massive multiple-input multiple-output …

A range of efficient wireless processes and enabling techniques are put under a magnifier
glass in the quest for exploring different manifestations of correlated processes, where sub …

This article focuses on advancing outdoor wireless systems to better support ubiquitous
