摘要

Short-packet communication (SPC) in multi-input multi-output (MIMO) networks with energy scavenging (ES) harnesses modern techniques such as MIMO processing, SPC, and radio frequency ES to achieve optimal spectrum usage, high reliability, low latency, and high energy efficiency . Nevertheless, a comprehensive performance analysis of SPC in MIMO system with ES under practical circumstances—successive interference cancellation imperfection (SICi), channel state information imperfection (CSIi), and nonlinear ES (nlES)—has yet to be conducted, particularly for advanced and conventional multiple access (MA) schemes—nonorthogonal MA (NOMA) and orthogonal MA (OMA). This paper addresses this gap by proposing an analytical framework, validated through Monte Carlo simulations, which quickly evaluates the total throughput and average block-error rate of SPC in MIMO system with nlES in key parameters such as transmit power, SICi level, CSIi level, power splitting factor, time division factor, power saturation threshold, antenna configuration, energy conversion efficiency. The results reveal that, contrary to long-packet communication, NOMA performs worse than OMA in SPC in MIMO system with nlES.
