In this paper, we characterize an achievable rate region for the two-user discrete memoryless compound Multiple Access Channel (MAC) with common message and with generalized feedback (CMACC-GF). The achievable rate region that we provide is proved using a combination of rate splitting, Superposition Block Markov Encoding (SBME), and backward decoding. It is(More)
Three-receiver broadcast channel (BC) is of interest due to its information theoretical differences with two receiver one. In this paper, we derive achievable rate regions for two classes of 3-receiver BC with side information available at the transmitter, Multilevel BC and 3-receiver less noisy BC, by using superposition coding, Gel'fand-Pinsker binning(More)
Change of attitude of organizations' managers toward human forces (as human capitals and resources) as well as technological advancement and accumulation of information in organizations reflects the necessity of valuing knowledge management. On the other hand, extraction of necessary, appropriate information and turning them into the knowledge required by(More)
We present an outer bound for the discrete memo-ryless two-way multiple access broadcast channel (TW-MAC/BC) using the dependence balance idea. The cut-set outer bound for multi-user channels allows arbitrarily correlated input distributions while the dependence balance idea limits the set of arbitrarily correlated input distributions to those satisfying a(More)
In this paper, the two-user interference channel (IC) with specially correlated sources and channel state information (CSI), both in the sense of Slepian-Wolf (SW) is considered in which channel states are available at the encoders non-causally. In correlation structures in the sense of Slepian-Wolf, two correlated sources are modeled by three independent(More)
—The additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is studied. This channel can be considered as an exponential version of the discrete memoryless channel with state known non-causally at the encoder considered by Gelfand and Pinsker. We make use of Gelf'and-Pinsker's classic(More)
In this paper we study the “Z” channel with side information non-causally available at the encoders. We use Marton encoding along with Gelf'and-Pinsker random binning scheme and Chong-Motani-Garg-El Gamal (CMGE) jointly decoding to find an achievable rate region. We will see that our achievable rate region gives the achievable rate of the(More)
AIMS Prognosis of esophageal cancer (EC) is poor. Population-based studies regarding EC survival and adequacy of cancer surgery (ACS) from developing countries are lacking. We aimed to evaluate EC patients' survival and ACS in a population-based setting for the first time from Iran. METHODS We randomly selected 409 cases from all 3048 newly diagnosed EC(More)
— In this paper, we examine discrete memoryless Multiple Access Channels (MACs) with two-sided feedback in the presence of two correlated channel states that are correlated in the sense of Slepian-Wolf (SW). We find achievable rate region for this channel when the states are provided non-causally to the transmitters and show that our achievable rate region(More)
