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)
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)
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 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)
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)
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)
In this paper, we characterize the capacity region for the two-user linear Gaussian compound Multiple Access Channel with common message (MACC) and with intersymbol interference (ISI) under an input power constraint. The region is obtained by converting the channel to its equivalent memoryless one by defining an n-block memoryless circular Gaussian compound(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)
Avoiding interference, one of the efficient methods is to design appropriate pulse waveform. In this paper an optimized pulse design method is proposed as ultra wideband (UWB) pulse shapes that made use of a linear only triple-pulse combination of multiple Gaussian derivatives. So as to gain the best weight coefficient, we proposed to optimize its weight(More)
