Salah satu teknik multiplexing yang saat ini populer digunakan untuk aplikasi akses komunikasi cepat berbasis cahaya tampak adalah Orthogonal Frequency Division Multiplexing (OFDM). Meskipun lebih kompleks dibandingkan modulasi berbasis Pulse Time Modulation (PTM), teknik OFDM disinyalir dapat lebih menghemat bandwidth komunikasi karena membagi bandwidth lebar menjadi spektrum yang sempit (sub-carrier) dan saling overlap. Sebagai akibat, transfer data akan lebih cepat dibandingkan PTM. Pada penelitian sebelumnya, penulis telah berhasil mendesain sistem low-cost VLC dengan modulasi digital 1-PWM (3,3 kbps) dan 2-PWM (6,2 kbps). Motivasi dari penelitian ini adalah menigkatkan laju data dengan menggunakan OFDM. Modulasi binary shift-keying modulation …
