Abstract

In this letter, we study the average block error rate (BLER) performance of short-packet communications (SPC) for pinching-antenna systems (PASS). A base station equipped with a pinching antenna serves an Internet of Things downlink user using SPC. Closed-form expressions for the average BLER of SPC for PASS networks are analytically derived under in-waveguide attenuation. Simulation results demonstrate that PASS-aided SPC networks significantly outperform conventional fixed-antenna-aided SPC systems in terms of BLER, especially in the low in-waveguide attenuation regime.
