TL;DR: In this article, a new approach of using time-modulated phased arrays to synthesize multicarrier directional modulation (DM) symbols for physical-layer security is presented, which is achieved with the careful design of the switching time sequences, instead of in digital baseband; thus, reducing the peak-to-average power ratio of signals going through the radio frequency (RF) chain, and only a single RF chain is required here.

TL;DR: In this article , the performance of the simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided non-orthogonal multiple access (NOMA) networks in support of ultra-reliable low-latency communications is investigated.

TL;DR: This work aims to obtain the maximum sum rate by optimizing the phase matrix of RIS subject to users’ transmitted power and proposes the semidefinite programming to relax the function while the majorization-minimization is used to derive the closed-form phase shifts.

TL;DR: A time and aperture resource allocation strategy for multitarget inverse synthetic aperture radar (ISAR) imaging that incorporates requirements for distributed network radar multitarget imaging tasks is proposed to improve the efficiency of a radar system.

TL;DR: In this paper, a new frequency diverse array (FDA) transmitter architecture with random logarithmically increasing frequency offset (log-RFDA) is presented, which provides a non-periodic thumbtacklike beampattern, eliminating the ambiguity in range domain, suffered in the CFDA radar.
