    • EM based MAP channel estimation for turbo/convolutional coded SFBC/STBC-OFDM systems 

      Doǧan H.; Çirpan H.A.; Panayirci, E. (2006)
      We consider the design of turbo receiver structures for space-frequency block coded (SFBC/STBC) OFDM systems in unknown frequency selective fading channels. The Turbo receiver structures for SFBC/STBC-OFDM systems under ...
    • Implementing the Han-Kobayashi scheme using low density parity check codes over Gaussian interference channels 

      Sharifi S.; Tanc, A. K.; Duman, T. M. (Institute of Electrical and Electronics Engineers Inc., 2015)
      We focus on Gaussian interference channels (GICs) and study the Han-Kobayashi coding strategy for the two-user case with the objective of designing implementable (explicit) channel codes. Specifically, low-density parity-check ...
    • 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 ...
    • Linear MMSE-optimal turbo equalization using context trees 

      Kim, K.; Kalantarova, N.; Kozat, S. S.; Singer, A. C. (IEEE, 2013)
      Formulations of the turbo equalization approach to iterative equalization and decoding vary greatly when channel knowledge is either partially or completely unknown. Maximum aposteriori probability (MAP) and minimum ...
    • Special Issue on Advances in Channel Coding 

      Arikan, E.; Lentmaier, M.; Montorsi, G. (Korean Institute of Communication Sciences, 2015)
      Since the invention of turbo codes in 1993 there has been an enormous interest and progress in the field of capacity approaching code constructions. Many classical constructions have been replaced by newer, better performing ...
