Secrecy Sum-Rate of Multi-User MISO Visible Light Communication Systems with Confidential Messages
This paper studies the information theoretic secrecy sum-rate for multi-user multiple-input single-output (MU-MISO) visible light communication (VLC) systems with confidential messages. The well-known Zero-Forcing (ZF) precoding method is employed to ensure confidentiality among legitimate users and, at the same time, to prevent eavesdropper(s) from obtaining any information. Different from rad...
متن کاملNetwork-Centric and User-Centric Multi-User Scheduling in Visible Light Communication aided Networks
Visible Light Communication (VLC) combined with advanced illumination has been expected to become an integral part of next generation heterogeneous networks at the time of writing, by inspiring further research interests. From both the Network-Centric (NC) and the User-Centric (UC) perspectives, various VLC cell formations, ranging from fixed-shape regular cells with different Frequency Reuse (...
متن کاملDistributed user-centric scheduling for visible light communication networks.
Visible light communication (VLC) networks, consisting of multiple light-emitting diodes (LEDs) acting as optical access points (APs), can provide low-cost high-rate data transmission to multiple users simultaneously in indoor environments. However, the performance of VLC networks is severely limited by the interference between different users. In this paper, we establish a distributed user-cen...
متن کاملDownlink Precoder and Equalizer Designs for Multi-User MIMO FBMC/OQAM
In this contribution we propose two new iterative precoder and equalizer designs for the Downlink (DL) scenario of Multi-User (MU)-MIMO systems which employ Filter Bank based Multi-Carrier (FBMC) with Offset-Quadrature Amplitude Modulation (O-QAM). In a MU-MIMO DL scenario, we must design our per-subcarrier filters to compensate the inter-symbol and intercarrier interference (ISI and ICI) prese...
متن کاملAn overview of visible light communication systems
Visible Light Communication (VLC) has gained great interest in the last decade due to the rapid developments in Light Emitting Diodes (LEDs) fabrication. Efficiency, durability and long life span of LEDs make them a promising residential lighting equipment as well as an alternative cheap and fast data transfer equipment. Appliance of visual light in data communication by means of LEDs has been ...
