Outage Probability of Dual-Hop Multiple Antenna Relay Systems with Interference at the Relay and Destination

International Journal of Antennas and Propagation, 2014
This paper analyzes the outage performance of a dual-hop relaying system in which the relay is equipped with multiple antennas, while the source and destination have a single antenna.

A multi‐source fusion and dynamic verification framework for scientific knowledge graph construction: Methods, evaluation, and applications

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract The exponential growth of scientific literature—over 2.5 million papers and 3.5 million patents annually—poses critical challenges for knowledge discovery. To address these, we propose SCIMKG (Scientific Knowledge Graph), a framework for constructing scientific knowledge graphs via multi‐source heterogeneous multi‐source.

Leveraging on the Impact of Imperfect Channel Estimation for MIMO Relaying Systems

IEEE Access, 2019
In this paper, we study a multi-user multiple-input multiple-output (MIMO) dual-hop wireless relaying system, where the decode-and-forward protocol is applied at the intermediate relay node. The well-known MIMO spatial multiplexing technique is employed,

Exact Outage Probability of Two-Way Decode-and-Forward NOMA Scheme with Opportunistic Relay Selection

KSII Transactions on Internet and Information Systems, 2019
In this paper, we propose a two-way relaying scheme using non-orthogonal multiple access (NOMA) technology. In this scheme, two sources transmit packets with each other under the assistance of the decode-and-forward (DF) relays, called as a TWDFNOMA ...
