Coded Modulation with APSK for OFDM-Based Visible Light Communications

Not Accessible

Your library or personal account may give you access

Abstract

Coded modulation with APSK is proposed for OFDM-based VLC systems. Simulation results show that the proposed scheme achieves better performance than conventional QAM counterpart in both DCO-OFDM and ACO-OFDM systems, while similar complexity is maintained.
