The emerging massive/large-scale multiple-input multiple-output (LS-MIMO) systems that
rely on very large antenna arrays have become a hot topic of wireless communications …

Fifth-generation (5G) cellular communications promise to deliver the gigabit experience to
mobile users, with a capacity increase of up to three orders of magnitude with respect to …

With years of tremendous traffic and energy consumption growth, green radio has been
valued not only for theoretical research interests but also for the operational expenditure …

OFDM signals suffer significant distortion when transmitted through practical power
amplifiers. In this paper, we examine the channel estimation performance of OFDM systems …

Underwater acoustic (UWA) channels are wideband in nature due to the small ratio of the
carrier frequency to the signal bandwidth, which introduces frequency-dependent Doppler …

To make transportation safer, more efficient, and less harmful to the environment, traffic
telematics services are currently being intensely investigated and developed. Such services …

This paper addresses the joint design of transmit and receive beamforming or linear
processing (commonly termed linear precoding at the transmitter and equalization at the …

This paper reviews the physical fundamentals and engineering implementations for efficient
information exchange via wireless communication using physical waves as the carrier …

Ultra-wideband (UWB) radio is a fast emerging technology with many unique attractive
features that promotes major advances in wireless communications, networking, radar …

Zero padding (ZP) of multicarrier transmissions has been proposed as an appealing
