A Novel Blockchain-Based Product Ownership Management System (POMS) for Anti-Counterfeits in the Post Supply Chain
TL;DR: This paper proposes a novel product ownership management system (POMS) of RFID-attached products for anti-counterfeits that can be used in the post supply chain and implements a proof-of-concept experimental system employing a blockchain-based decentralized application platform, Ethereum.
Journal ArticleDOI
Nonregenerative dual-hop cooperative links with selection diversity
TL;DR: The end-to-end performance of dual-hop cooperative diversity systems equipped with nonregenerative relays and a selection combining receiver at the destination terminal over independent and nonidentical Nakagami- fading channels is studied.
Journal ArticleDOI

TL;DR: A novel multiscale and hierarchical framework is introduced, which describes the classification of TLS point clouds of cluttered urban scenes, and novel features of point clusters are constructed by employing the latent Dirichlet allocation (LDA).
Journal ArticleDOI
Analytical level crossing rates and average fade durations for diversity techniques in Nakagami fading channels
TL;DR: This work provides novel analytical expressions for selection combining and equal-gain combining, and rederive in a more general manner the case of maximal-ratio combining (MRC), and shows that the general results reduce to some specific cases previously published.
Journal ArticleDOI
Full-Duplex Cooperative NOMA Relaying Systems With I/Q Imbalance and Imperfect SIC
TL;DR: Comparisons with equivalent half-duplex (HD) C-NOMA schemes have revealed that for the far user the FD C-nOMA scheme is less sensitive to ipSIC, and closed-form exact and analytical approximate expressions for the outage probability and ergodic sum rate are derived.
