Abstract

In this letter, we perform an unified analysis of an uplink non-orthogonal multiple access (NOMA) system with short-packets over a wide range of fading channels, such as lognormal-Nakagami- m , generalized K-G , -μ, Nakagami- q (Hoyt), μ , Rician, Nakagami- m , and Rayleigh fading. The system model consists of a high-priority user with low-rate, low-latency and high-reliability requirements, and a low-priority user with high-rate and delay-tolerant. We first derive closed-form expressions of the average block error-rate (BLER) and the asymptotic at the high signal-to-noise ratio (SNR) regime. Next, we optimize the power back-off level and the packet-length to maximize the throughput of the low-priority user subject to the quality-of-service (QoS) requirements of the high-priority user. Theoretical analysis is corroborated by simulation results.
