In this paper, a Gaussian multiple input multiple output multiple eavesdropper (MIMOME) channel is considered where a transmitter communicates to a receiver in the presence of an eavesdropper. We present a technique for determining the secrecy capacity of the multiple input multiple output (MIMO) channel under Gaussian noise. We transform the degraded MIMOME channel into multiple single input m...

This is a tutorial article presenting comparison between single input single output and multi input multi output wireless channel. We have compared Shannon ergodic capacity of SISO link and its different realizations with MIMO wireless channel. It is shown that wireless channel capacity increases linearly with the increase of multiple antennas both at transmitter and receiver. MIMO wireless lin...

In a multi-channel environment, an adaptive blind equalizer-bank is presented which, under mild conditions, equalizes the channel-bank automatically. This adaptive blind equalizer is adaptive only to its own output, not to its input, i.e., the channel output.

this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

We consider the problem of proving correctness properties for concurrent systems with features such as higher-order communication and dynamic resource generation. As examples we consider operational models of security and authentication protocols based on the higher-order-calculus. Key features such as nonces/time stamps, encryption/decryption, and key generation are modelled using channel name...

In this paper we introduce a lemma. This lemma states that for a unitary covariant channel Ψ and a channel M such that M(ρ0) is of rank one for some state ρ0 ∈ S(H) the additivity of the minimal output entropy of Ψ implies that of Ψ ◦M , and the multiplicativity of the maximal output p-norm of Ψ, that of Ψ ◦M . For the product channel of the depolarising channel and an arbitrary channel the add...

This paper describes an interactive multi-channel multi-user networked system for real-time composition and immersive performance built using a modified version of the Quake III gaming engine. By tracking users’ positional and action data within a virtual space, and by streaming that data over a network using OSC messages formatted as UDP packets to a multi-channel Pure Data patch, actions in v...

In this study, we use a Dynamic Stochastic General Equilibrium (DSGE) model to investigate the household portfolio channel of monetary and credit shocks transmission in Iran. In this regard, we developed a canonical New Keynesian DSGE model with financial and banking sectors. The model is estimated by Bayesian method for the period 1990-2012. The result showed that the current and expected pric...
