A two-way full-duplex multiple-input multiple-output (MIMO) relay provides effective spectral efficiency and system capacity improvement. However, self-interference (SI) as a serious problem limits the development of a full-duplex relay. In this paper, the novel SI suppression schemes based on the Dempster-Shafer (DS) evidence theory are proposed to suppress SI in the two-way full-duplex MIMO relay...
In this paper, a two-way relay system which achieves bi-directional communication via a multiple-antenna relay in two time slots is studied. In the multiple access (MA) phase, the novel receive schemes based on Dempster-Shafer (D-S) evidence theory are proposed at the relay node. Instead of traditional linear detection, the first proposed MIMO-DS NC scheme adopts D-S evidence theory to detect the...
In this paper, a novel self-interference (SI) suppression scheme based on Dempster-Shafer (D-S) evidence theory is proposed to cancel self-interference in two-way full-duplex (FD) MIMO relay. D-S evidence theory can appropriately characterize uncertainty and make full use of multiple evidence source information by Dempster's combination rule to obtain reliable decisions. Instead of traditional spatial-domain...
