研究目的
Investigating the outage probability and spectral efficiency of SEE-OFDM VLC-NOMA networks compared to orthogonal multiple access techniques.
研究成果
The SEE-OFDM VLC-NOMA network demonstrates superior spectral efficiency and outage probability performance compared to other multiple access techniques, with a tight upper bound derived for outage probability.
研究不足
The study assumes static or quasi-static channel state information and only considers line-of-sight links, potentially overlooking the impact of dynamic environments and non-line-of-sight components.
1：Experimental Design and Method Selection:
The study focuses on the performance analysis of SEE-OFDM VLC-NOMA networks through theoretical modeling and simulation.
2：Sample Selection and Data Sources:
Numerical results are obtained using Monte Carlo simulations with 106 trials.
3：List of Experimental Equipment and Materials:
Simulation parameters include cell radius, FFT/IFFT size, LED semi-angle, noise power, optical concentrator gain, optical filter gain, PD responsivity, PD detection area, PD FOV, reflective index, and vertical separation.
4：Experimental Procedures and Operational Workflow:
The study derives an exact expression for the outage probability and provides an upper bound of the data rate for K NOMA users.
5：Data Analysis Methods:
The performance is evaluated in terms of outage probability and achievable capacity, comparing SEE-OFDM NOMA with ACO-OFDM NOMA and OMA techniques.
