End-to-End Modeling of FSO Communication Systems with QNSC Encryption under Different Turbulence Conditions

For QNSC-FSO, we propose Transformer, BiLSTM, and BiGRU-based E2E modeling. Analysis under weak-to-strong turbulence shows Transformer outperforms BiLSTM and BiGRU by an order of magnitude, achieving 9.3×10⁻⁴ KL performance.
