The time reversal (TR) transmission technique can harvest the signal energy from multiple
paths and focus the signal power on an intended space-time point. Different from the works …

In this work, we analyze the secrecy outage performance of a dual-hop relay system composed
of multiple-input-multiple-output radio-frequency (RF) links and a free-space optical (FSO…

We analyze a secure dual-hop mixed radio frequency-free space optical (RF-FSO) downlink
simultaneous wireless information and power transfer system. The FSO link and all RF links …

In this article, we study the secure communication performance of nonorthogonal multiple
access (NOMA) communication systems with aerial eavesdroppers. First, the ground-to-…

Interference alignment is a kind of transmission technique which is able to align the
interference from other transmitters into the same channel space. This paper proposes a novel …

In this paper, for a wireless communication system with energy harvesting and rateless error
correction codes, the joint optimization of transmit power, modulation scheme and code rate …

Thanks to its characteristics of temporal compression and spatial focusing, the time reversal
(TR) transmission system has the intrinsic capability of anti‐eavesdropping. This study …

This paper studies the physical layer security scheme of a multi-input single-output (MISO)
wireless communication system. To improve the propagation quality of the channels, …

The time-reversal division multiple access (TRDMA) system employs multipath channels to
realize multi-user transmission via time-reversal filtering. The performance of TRDMA is …

This letter investigates the design of the pre-filters for MISO-OFDM systems to shorten the
cyclic prefix (CP). The pre-filters are optimized to minimize the length of the impulse response …
