Abstract
Bu makalede, OFDM'nin optik kablosuz iletişim sistemleri için verimli bir tek kutuplu versiyonu olan Flip-OFDM dalga biçiminde titreşim sorunu olmadan M-seviye renk kaydırmalı anahtarlama (M-CSK) modülasyonunun kullanılması önerilmiştir. Önerilen şemanın performansı, bit-hata oranı (BER) ve tepe ortalama güç oranı (PAPR) kriterlerine dayalı M-QAM modülasyonlu Flip-OFDM ve M-CSK modülasyonlu VLC OFDM yöntemleri ile karşılaştırılır. BER performansı da önce kodlanmamış önerilen şema, ardından iki kanallı kodlama teknikleri, yani Reed-Solomon (RS) kanal kodlayıcı ve Evrişimli Kodlar (CC) kullanılarak iki kanal, yani AWGN ve optik LOS kanalı kullanılarak analiz edilmiştir. Tüm kanal kodlama teknikleri, QAM modülasyonu kullanılarak gerçekleştirilir. Simülasyon sonuçları, önerilen M-CSK Flip-OFDM yönteminin hem AWGN kanalı hem de optik LOS kanalı için yüksek SNR değerlerinde iyi performans elde ettiğini ve ayrıca RS ve CC uygulanarak BER performansının da iyileştirildiğini göstermektedir.
