Abstrak
Visible Light Communication (VLC) merupakan kamunikasi jaringan nirkabel yang informasinya dikirimkan menggunakan media cahaya berupa Light Emitting Diode (LED) melalui gelombang tampak. VLC memiliki keterbatasan berupa bandwidth yang sempit. Non – Orthogonal Multiple Access (NOMA) salah satu multiple access yang efektif menghemat bandwidth. Namun, Multi User Detection (MUD) jenis Successive Interference Cancellation (SIC) pada sisi penerima di NOMA konvensional menyebabkan Error Detection (ED). Pada Tugas Akhir ini menganalisis performansi MUD jenis FREE SIC pada NOMA VLC dalam ruangan berukuran 5 x 5 x 5 m3 . MUD ini menggunakan dua modulasi berbeda untuk setiap kondisi kualitas kanal, yaitu kualitas kanal yang buruk menggunakan modulasi OOK dan untuk kualitas kanal yang baik menggunakan modulasi MPPM. Didapatkan bahwa penggunaan modulasi ini mampu memperbaiki BER yang ada, dimana BER saat menggunakan FREE SIC lebih baik dibandingkan dengan SIC. Hal ini menunjukan penggunaan FREE SIC lebih baik dari pada penggunaan SIC.
