Mobility Support for Full-Duplex Multiuser Bidirectional VLC Networks

Multiuser Full-Duplex Communication

The inevitable high bandwidth requirement in the future cellular network has made researchers to come up with revolutionary ideas in recent times. One such idea is the introduction of full-duplex (FD) communication. A FD systems make the simultaneous in-band transceiving feasible, i.e, simultaneous uplink and downlink operation using the same spectrum resources. In recent years, extensive work ...

A New Design Paradigm for Secure Full-Duplex Multiuser Systems

We consider a full-duplex (FD) multiuser system where an FD base station (BS) is designed to simultaneously serve both downlink (DL) and uplink (UL) users in the presence of half-duplex eavesdroppers (Eves). The problem is to maximize the minimum (max-min) secrecy rate (SR) among all legitimate users, where the information signals at the FD-BS are accompanied with artificial noise to debilitate...

Transmission strategies for full-duplex multiuser MIMO communications systems

Full-Duplex WiFi Networks

The device in conventional half-duplex WiFi networks cannot perform carrier sensing while in data transmission; thus it suffers from long collision duration. To mitigate this problem, this chapter introduces full-duplex (FD) technology into WiFi networks. A novel CSMA/CD protocol design is first presented for singlechannel FD-WiFi, which facilitates continuous carrier sensing and transmission s...

Linear Transceiver Design for Bidirectional Full-Duplex MIMO OFDM Systems

In this paper we address the linear precoding and decoding design problem for a bidirectional orthogonal frequencydivision multiplexing (OFDM) communication system, between two multiple-input multiple-output (MIMO) full-duplex (FD) nodes. The effects of hardware distortion as well as the channel state information error are taken into account. In the first step, we transform the available time-d...
