Kapalı Mekan Görünür Işık Haberleşmesi için CSK Modülasyonunun Çokyollu Kanal Şartlarında İncelenmesi
Küçük, Mehmet Ali; Türk, Kadir; Albayrak, Cenk (Elektrik Elektronik Mühendisliği Kongresi 2019, 2019-11-16)Görünür ışık haberleşmesi (Visible Light Communication, VLC), görünür banttaki ışığı aydınlatmanın yanında haberleşme için de kullanan bir teknolojidir. VLC'nin kırmızı-yeşil-mavi ışık yayan diyotlar (RGB LED'ler) üzerinden ... -
Low-Complexity Early Termination Method for Rateless Soft Decoder
Albayrak, Cenk; Simsek, Cemaleddin; Turk, Kadir (IEEE-Inst Electrical Electronics Engineers Inc, 2017)We propose a new early termination method (ETM) with low computational complexity for Luby transform belief propagation (BP) decoder. The proposed method, which we call least reliable messages (LRM) ETM, observes only sign ... -
Performance of Visible Light Communication with Colour Shift Keying Modulation and Polar Code
Simsek, Cemaleddin; Tugcu, Emin; Albayrak, Cenk; Yazgan, Ayhan; Turk, Kadir (IEEE, 2018)Visible light communication (VLC) is an emerging technology to fulfill both illumination and communication purposes considered as either an alternative or a support system for some of scenarios carried by RF communication ... -
Sign Alterations of LLR Values Based Early Termination Method for LT BP Decoder
Albayrak, Cenk; Simsek, Cemaleddin; Turk, Kadir (IEEE, 2017)In this letter, a new early termination method is proposed for Luby transform (LT) belief propagation (BP) decoder. The proposed method is decided whether BP decoder output converges to original data bits by observing only ...
