In this paper, we consider signal-to-leakage-plus-noise ratio (SLNR) maximized precoding
for multi-antenna downlinks under per-antenna power constraints (PAPCs). In contrast to the …

In this paper, we introduce one full-duplex (FD) relaying transmission scheme for high speed
railway and compare its ergodic capacity and outage performance with half-duplex (HD) …

In this paper, we propose a robust minimum mean square error (MMSE)-based
beamforming technique for multiantenna relay broadcast channels, where a multiantenna …

Nonlinear transceiver based on Tomlinson-Harashima (TH) precoding outperforms the
linear minimum mean-square-error (MSE) architecture in terms of minimum achievable …

In this paper, the problem of joint transmit power and bandwidth allocation over multiple
channels is investigated for a secondary user in underlay mode, when partial information of …

In this letter, we study the problem of estimating a complex parameter in a wireless sensor
network under individual power constraints and bounded channel uncertainty, where the …

Owing to the vulnerability of relay-assisted communications, improving wireless security
from a physical layer signal processing perspective is attracting increasing interest. Hence …

The security issue is critically important for wireless communications, especially for multi-hop
communications. In this paper, we propose a cooperative secrecy beamforming scheme for …

In this paper, the impact of both maximal ratio combining (MRC) and relay selection on the
physical layer security in wireless communication systems is investigated by analyzing …

In this paper, we investigate a rateless code design for a two-time slot two-way relay channel
(TWRC), where network coding operation is employed at the relay. Rateless codes are used …
