Sequential Beamforming for Multiuser MIMO With Full-Duplex Training

Multiuser MIMO Beamforming with Full-duplex Open-loop Training

In this paper, full-duplex radios are used to continuously update the channel state information at the transmitter, which is required to compute the downlink precoding matrix in MIMO broadcast channels. The full-duplex operation allows leveraging channel reciprocity for open-loop uplink training to estimate the downlink channels. However, the uplink transmission of training creates interference...

Transmission strategies for full-duplex multiuser MIMO communications systems

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 ...

Downlink Transmit Beamforming for Multiuser - MIMO System

In multiuser multiple input multiple output (MUMIMO) downlink, the presence of multiuser cause the co-channel interference (CCI). The co-channel interference should be suppressed at the transmitter by the space precoding. Precoding is required to overcome it. The specifically challenge is to design transmit beamforming vectors for each user. Signal to leakage plus noise ratio (SLNR) method is o...

Full Duplex MIMO Radios

This paper presents the design and implementation of the first in-band full duplex WiFi-PHY based MIMO radios that practically achieve the theoretical doubling of throughput. Our design solves two fundamental challenges associated with MIMO full duplex: complexity and performance. Our design achieves full duplex with a cancellation design whose complexity scales almost linearly with the number ...
