    • Challenges and some new directions in channel coding 

      Arikan, E.; Ul Hassan, N.; Lentmaier, M.; Montorsi, G.; Sayir, J. (Korean Institute of Communication Sciences, 2015)
      Three areas of ongoing research in channel coding are surveyed, and recent developments are presented in each area: Spatially coupled low-density parity-check (LDPC) codes, nonbinary LDPC codes, and polar coding.

    • Code design for binary energy harvesting channel 

      Dabirnia, Mehdi; Duman, Tolga M. (IEEE, 2017)
      We consider a binary energy harvesting communication system with a finite battery transmitter over a noisy channel, and design explicit and implementable codes based on concatenation of a nonlinear trellis code (NLTC) with ...

    • Design of LDPC codes for two-way relay systems with physical-layer network coding 

      Tanc, A. K.; Duman, T. M.; Tepedelenlioglu, C. (IEEE, 2013)
      This letter presents low-density parity-check (LDPC) code design for two-way relay (TWR) systems employing physical-layer network coding (PLNC). We focus on relay decoding, and propose an empirical density evolution method ...

    • Error resilient layered stereoscopic video streaming 

      Tan, Ahmet Serdar; Aksay, A.; Bilen, Ç.; Bozdağı-Akar, G.; Arıkan, Erdal (IEEE, 2007)
      In this paper, error resilient stereoscopic video streaming problem is addressed. Two different Forward Error Correction (FEC) codes namely Systematic LT and RS codes are utilized to protect the stereoscopic video data ...

    • Multi-input multi-output deletion channel 

      Wang F.; Duman, T. M. (Institute of Electrical and Electronics Engineers, 2012)
      We describe a new channel model suitable in certain applications, namely the multi-input multi-output (MIMO) deletion channel. This channel models the scenarios where multiple transmitters and receivers suffering from ...

    • On LDPC codes for Gaussian interference channels 

      Sharifi, S.; Tanç, A. K.; Duman, Tolga M. (IEEE, 2014)
      In this paper, we focus on the two-user Gaussian interference channel (GIC), and study the Han-Kobayashi (HK) coding/decoding strategy with the objective of designing low-density parity-check (LDPC) codes. A code optimization ...

    • Performance analysis of two-level forward error correction for lostcell recovery in ATM networks 

      Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1995-04)
      The major source of errors in B-ISDN/ATM systems is expected to be buffer overflow during congested conditions, resulting in ATM cell losses which degrade the quality of service. It has been shown by many authors that the ...

    • A performance comparison of polar codes and reed-muller codes 

      Arıkan, E. (Institute of Electrical and Electronics Engineers, 2008)
      Polar coding is a code construction method that can be used to construct capacity-achieving codes for binary-input channels with certain symmetries. Polar coding may be considered as a generalization of Reed-Muller (RM) ...

    • Simulation study of forward error correction for lost packet recovery in B-ISDN/ATM 

      Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1993-05)
      We present the results of a simulation study for a virtual circuit connection over an ATM network where forward error correction is performed at both the ATM cell level and the packet data unit (PDU) level. A main conclusion ...

    • Unequal error protection for stereoscopic video streaming 

      Tan, Ahmet Serdar; Aksay, A.; Bilen, Ç.; Bozdağı-Akar, G.; Arıkan, Erdal (IEEE, 2007)
      The utilization of forward error correction (FEC) schemes for stereo video streaming is investigated. Stereo video is categorized in 3 layers and each layer is protected with different protection ratios for efficient ...
