Optimization of Power Allocation Factors Based on User Path Loss for BER Minimization in NOMA over Rician Fading Channels

This dataset contains simulation results for verifying the derived bit error rate (BER) expression and optimal power allocation factors in downlink NOMA systems over Rician fading channels. The data includes:1. **Numerical simulations** of the integral BER expression (Eq.15) 2. **Monte Carlo simulations** with 10^6 iterations3. **Optimal \u03b1 vs. \u03c1\u2082 curves** (Eq.21 verification)Parameters:- Rician factor K = 10 - Scattering component \u03c3 = 1- Ps\/N\u2080 ranges: 0-30 dB (BER comparison), 15\/20 dB (\u03b1 optimization)- Three (\u03b1, \u03c1\u2082) sets: (0.05,0.1), (0.25,0.9), (0.15,0.3)The data is structured as MATLAB .mat files containing:- Fig3.BER.mat: BER values for all parameter combinations- SNR20_meng.mat: Monte Carlo simulation results at SNR=20dB- SNR15_meng.mat: Monte Carlo simulation results at SNR=15dBThis dataset enables reproducibility of Figs. 3-4 in the associated manuscript and facilitates further research on NOMA power allocation under Rician fading.
