In-Band Full-Duplex Wireless: Challenges and Opportunities
Ashutosh Sabharwal,Philip Schniter,Dongning Guo,Daniel W. Bliss,Sampath Rangarajan,Risto Wichman +5 more
TL;DR: This tutorial surveys a wide range of IBFD self-interference mitigation techniques and discusses numerous other research challenges and opportunities in the design and analysis of IB FD wireless systems.
Journal ArticleDOI
Mitigation of Loopback Self-Interference in Full-Duplex MIMO Relays
TL;DR: Targeting at minimal interference power, a broad range of multiple-input multiple-output mitigation schemes are analyzed and the results confirm that self-interference can be mitigated effectively also in the presence of imperfect side information.
Journal ArticleDOI
Hybrid Full-Duplex/Half-Duplex Relaying with Transmit Power Adaptation
TL;DR: This work proposes the combination of opportunistic mode selection and transmit power adaptation for maximizing instantaneous and average spectral efficiency after noting that the trade-off favors alternately the modes during operation.

Transmit diversity method and system
Ari Hottinen,Risto Wichman +1 more
TL;DR: In this article, the authors proposed a transmit diversity method for a wireless communication system comprising a transmitting element and at least one receiver, wherein a transmission signal is transmitted from the transmitting element to the at least receiver in accordance with a weight information determined in response to a feedback information, and is fed back using multiplexed feedback signals.
