Average Block Error Rate of Downlink NOMA Short-Packet Communication Systems in Nakagami-

摘要

Short-packet communication systems provide low latency communications in fifth-generation wireless cellular networks. In this letter, we study the average block error rate (BLER) of downlink non-orthogonal multiple access (NOMA) short-packet communication systems. By invoking stochastic geometry, we consider that the locations of NOMA users are uniformly distributed in a disc and theoretically derive the analytical expressions for average BLER in Nakagami-m fading channels. Numerical results illustrate that our theoretically derived analytical average BLERs are almost the same as the simulation results.
