In this paper, we investigate multiple-input single-output (MISO) simultaneous wireless information and power transfer (SWIPT) broadcast channels with confidential messages (BCC) scenario, in which a multiple-antenna transmitter simultaneously transmits confidential messages and power to multiple single-antenna receivers. Considering the imperfect channel state information (CSI), we study the joint...
Hybrid multiple input multiple output (MIMO) beamforming can be divided into shared and split MIMO beamforming architectures, according to different concatenations of radio frequency (RF) chains and antennas. This paper considers split MIMO beamforming for millimeter wave system, i.e., each antenna subarray is only connected with one RF chain. To obtain analog precoding matrix and combining matrix,...
This paper considers interference mitigation with power allocation in cognitive radio systems. In such a system, cognitive radio is designed to transmit data to its corresponding users without causing any interference to the current primary transmission. To avoid these interference between these links, the secondary transmitters sense the primary user's unused eigenvector space and reuse these spatial...
For multicell MIMO interfering broadcast channels (IFBC), the zero-forcing-based approach can achieve the near optimal performance at high signal-noise-ratio (SNR) regime. However, the drawback of the zero-forcing-based approach is the poor performance in low SNR regime compared to the conditional match filter receive scheme. In order to address this problem, we propose an algorithm for minimizing...
The deployment of small-cell access points(SCAs) is widely acknowledged as a promising network densification way to satisfy the future capacity needs of 5G wireless cellular network. In this paper, we study the power allocation problem in heterogeneous downlink network while satisfying QoS constraints and power constraints simultaneously. The scheme is formulated as maximizing the system energy efficiency...
In this paper, we design a secure transmission scheme for multiple-input single-output (MISO) broadcast channel with simultaneous wireless information and power transfer (SWIPT), where a multi-antenna transmitter simultaneously transmit independent confidential messages to multiple potentially malicious receivers, in the presence of external eavesdroppers. Our objective is to minimize the total transmit...
In this paper, we propose a secure transmission scheme for simultaneous wireless information and power transfer (SWIPT) in a multiple-input single-output (MISO) broadcast channel with confidential messages, where each receiver utilizes the power splitting approach to decode information and harvest energy simultaneously, and it also acts as a potential eavesdropper for the independent message sent...
