    • Code design for discrete memoryless interference channels 

      Dabirnia, Mehdi; Tanc, A. K.; Sharifi S.; Duman, Tolga M. (Institute of Electrical and Electronics Engineers, 2018)
      We study the design of explicit and implementable codes for the two-user discrete memoryless interference channels (DMICs). We consider Han-Kobayashi (HK) type encoding where both public and private messages are used and ...
    • Code design for interference channels 

      Herfeh, Mahdi Shakiba (Bilkent University, 2019-11)
      As the number of wireless devices dramatically increases, they experience more interference in their communications. As a result, managing interference in wireless networks is an important challenge in future wireless ...
    • LDPC code design for fading interference channels 

      Shakiba-Herfeh, Mahdi; Tanc, A. K.; Duman, Tolga M. (IEEE, 2019-03)
      We focus on the two-user Gaussian interference channel (IC) with fading and study implementation of different encoding/decoding schemes with low-density parity-check (LDPC) codes for both quasi-static and fast fading ...
    • LDPC code design for fast fading interference channels 

      Shakiba-Herfeh, Mahdi; Tanc, A. K.; Duman, Tolga M. (IEEE, 2018-05)
      We focus on two-user Gaussian interference channels (ICs) with fast fading and study implementation of explicit all public and Han- Kobayashi (HK) coding schemes with low-density parity-check (LDPC) codes. Stability ...
    • LDPC code design for the two-user Gaussian multiple access channel 

      Sharifi S.; Tanc, A. K.; Duman, T. M. (Institute of Electrical and Electronics Engineers Inc., 2016)
      We study code design for two-user Gaussian multiple access channels (GMACs) under fixed channel gains and under quasi-static fading. We employ low-density parity-check (LDPC) codes with BPSK modulation and utilize an ...
    • LDPC codes for interference channels in the primary decodes cognitive regime 

      Shakiba-Herfeh, Mahdi; Tanç, A. K.; Duman, Tolga M. (Institute of Electrical and Electronics Engineers Inc., 2019)
      We investigate cognitive interference channels (CICs), a variant of two-user ICs in which one of the transmitters (called the cognitive transmitter) has non-causal knowledge of the other's (private user's) message. Prompted ...
    • 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 capacity and coding for segmented deletion channels 

      Wang, F.; Aktaş, Defne; Duman, T. M. (IEEE, 2011)
      We consider binary deletion channels with a segmentation assumption which appears to be suited for more practical scenarios. Unlike the binary independent and identically distributed (i.i.d.) deletion channel where each ...
