Achieving full diversity in multi-antenna two-way relay networks via symbol-based physical-layer network coding [PDF]
, 2013 This paper considers physical-layer network coding (PNC) with M-ary phase-shift keying (MPSK) modulation in two-way relay channel (TWRC). A low complexity detection technique, termed symbol-based PNC (SPNC), is proposed for the relay.

Weak Secrecy in the Multiway Untrusted Relay Channel With Compute-and-Forward [PDF]
IEEE Transactions on Information Forensics and Security, 2015 We investigate the problem of secure communications in a Gaussian multi-way relay channel applying the compute-and-forward scheme using nested lattice codes. All nodes employ half-duplex operation and can exchange confidential messages only via an untrusted relay. The relay is assumed to be honest but curious, i.e., an eavesdropper that conforms to the

A Review of Offline Blockchain Transaction Systems
IET Blockchain, Volume 6, Issue 1, January/December 2026.Blockchain systems currently rely on constant network connectivity, which limits their utility in remote areas, during network outages or cyber attacks. This paper presents the first systematic study on offline blockchain implementations, analyzing their security and privacy challenges.

Dual IRS‐Assisted Secure Communication for Untrusted Two‐Way AF Relay Network
IET Communications, Volume 20, Issue 1, January/December 2026.To address the performance loss caused by the difficulty of balancing phase configuration requirements in single‐IRS‐assisted asymmetric bidirectional secure relay communication, this paper proposes a dual‐IRS collaborative optimization framework. Specifically, each user is configured with a dedicated IRS to enable personalized signal reflection, and ...

Robust MMSE Precoding Strategy for Multiuser MIMO Relay Systems with Switched Relaying and Side Information [PDF]
, 2013 In this work, we propose a minimum mean squared error (MMSE) robust base station (BS) precoding strategy based on switched relaying (SR) processing and limited transmission of side information for interference suppression in the downlink of multiuser ...
