Item Open Access Exchange of correlated binary sources in two-way relay networks using LDPC codes(Institute of Electrical and Electronics Engineers Inc., 2017) Salim, A.; Duman, T. M.We consider the problem of exchanging messages in two-way relay (TWR) systems when the sources are correlated binary sequences. In a TWR system, two users communicate simultaneously in both directions to exchange their messages with the help of a relay. Harnessing the fact that the users have access to their own non-compressed messages as side information, each user can compress its message according to the Slepian-Wolf coding strategy by using low-density parity-check codes, particularly, the syndrome approach. Through numerical examples, we show that the proposed scheme offers significant improvements in compression rates compared to the existing solutions in the literature.Item Open Access Kutupsal kodlar ile asimetrik ve asimetrik olmayan Slepian-Wolf kodlama(IEEE, 2012) Önay, SaygunBu bildiride, düzgün marjinal dağılıma sahip kaynaklar için Slepian–Wolf (SW) hız egrisindeki herhangi bir noktaya ulaşabilen Gehrig tarafından bulunmuş bir asimetrik olmayan dağıtık kaynak kodlama (DKK) tasarımını ele alıyor ve kutupsal kodlamanın bu yöntem içerisinde nasıl kullanılabileceğini gösteriyoruz. Daha sonra önerilen yöntemin simülasyon sonuçlarıyla performansını sunuyoruz.Item Open Access Source polarization(IEEE, 2010) Arıkan, ErdalThe notion of source polarization is introduced and investigated. This complements the earlier work on channel polarization. An application to Slepian-Wolf coding is also considered. The paper is restricted to the case of binary alphabets. Extension of results to non-binary alphabets is discussed briefly.
