This paper proposes an adaptive orthogonal frequency division multiplexing with Reed-Solomon coding (Adaptive OFDM-RS) scheme for mobile visible light communication (VLC) scenarios. This scheme supports real-time code rate selection based on channel state information, choosing k from the set {163, 183, 203, 223, 243}. By continuously monitoring the channel signal-to-noise ratio (SNR), the system dynamically adjusts the RS coding strength to maintain error-free transmission while maximizing spectral efficiency. Simulation results demonstrate that the proposed real-time code rate selection mechanism achieves: error-free transmission at SNR ≥ 13 dB for a 16-QAM modulated VLC-OFDM system; and error-free transmission at SNR ≥ 20 dB for a 64-QAM modulated system. These results validate the high robustness and effectiveness of the system under dynamic channel conditions.

摘要

This paper proposes an adaptive orthogonal frequency division multiplexing with Reed-Solomon coding (Adaptive OFDM-RS) scheme for mobile visible light communication (VLC) scenarios. This scheme supports real-time code rate selection based on channel state information, choosing k from the set {163, 183, 203, 223, 243}. By continuously monitoring the channel signal-to-noise ratio (SNR), the system dynamically adjusts the RS coding strength to maintain error-free transmission while maximizing spectral efficiency. Simulation results demonstrate that the proposed real-time code rate selection mechanism achieves: error-free transmission at SNR ≥ 13 dB for a 16-QAM modulated VLC-OFDM system; and error-free transmission at SNR ≥ 20 dB for a 64-QAM modulated system. These results validate the high robustness and effectiveness of the system under dynamic channel conditions.
