Performance Evaluation for UAV-Based UL-NOMA with Channel Coding

Abstract

Non-orthogonal multiple access is a potential technique to improve the spectral efficiency of beyond-5G systems by superposing multiple signals. For a received signal to be decoded, successive interference cancellation (SIC) process is required to subtract other signals at the receiver side. The channel coding is required to reduce the error probability when mobility is considered in non-orthogonal multiple access (NOMA) and applied after the SIC process. In this paper, we evaluate the performance of the unmanned aerial vehicle-based uplink NOMA with the concatenation of Reed–Solomon and convolutional code. Simulation results show comparisons between different conditions such as perfect and imperfect SIC processes.
