Performance Analysis of Anti-Interference Cooperative NOMA System for Aviation Data Links

In collaborative combat operations, the challenges posed by communication adversities in aviation data links have become increasingly conspicuous. Ensuring reliable connectivity of has thus emerged as a critical issue, particularly light growing interference effects on link outage. To address this challenge, paper proposes cooperative non-orthogonal multiple access (NOMA) technology that aims to enhance tolerance and strengthen stable capabilities links. achieve these goals, an anti-interference NOMA system model applicable is established, performance analyzed under Rice fading channel conditions. The analysis centers system’s outage probability, for which closed-form expression derived. Numerical methods are employed calculate solve expression, while simulation experiments conducted analyze effect factors such transmission power, forwarding distance, allocation coefficients probability. results show using scheme better than non-collaborative scheme, adjusting above parameters can effectively improve performance.
