Towards understanding energy requirements for computation with noisy elements, we consider the computation of an arbitrary k-input, k-output binary invertible function. In our model, not all gates need to be noisy. However, the input nodes on the computation graph must be separated from the output nodes by a noisy cut. For this setup, we show that for the “information-friction” model proposed r...

The quantification of information leakage provides a quantitative evaluation of the security of a system. We propose the usage of Markovian processes to model deterministic and probabilistic systems. By using a methodology generalizing the lattice of information approach we model refined attackers capable to observe the internal behavior of the system, and quantify the information leakage of su...

In this paper, joint water filling and maximal ratio transmission (joint WF-MRT) downlink transmit diversity for a single-carrier distributed antenna network (SC DAN) is proposed. The joint WF-MRT transmit weight allocates the transmit power in both transmit antenna dimension and frequency dimension, i.e., the power allocation is done both across frequencies based on WF theorem and across trans...

Capacity analysis and computation for communication channels with side information at the receiver is an important area of research. Cover-Chiang have proved the increment of capacity with non-causal information at the receiver. We investigate this capacity increment for the channel with causal side information and proposed an efficient algorithm for computing the capacity of discrete memoryles...

We investigate the capacity of three symmetric quantum states in three real dimensions to carry classical information. Several such capacities have already been defined, depending on what operations are allowed in the protocols that the sender uses to encode classical information into these quantum states, and that the receiver uses to decode it. These include the C1,1 capacity, which is the ca...

In this research, IR and frontier molecular orbital computations were employed for investigating the influence of B12N12 on the energetic and thermodynamic parameters of TATB. The Computed enthalpy changes and Gibbs free energy variations showed TATB interaction with this nanostructure is exothermic, spontaneous and experimentally possible. The specific ...

In this article, the performance of cognitive radio system benefits from non-orthogonal multiple access (NOMA) scheme. We then examine metrics to adjust its quality signal processing. focus on secondary network containing NOMA users which have some impacts normal user and primary nodes. refer enhancement fairness spectrum utilization by enabling sharing. particular, power allocation factors are...

In order to satisfy the stringent demand for an accurate prediction of MIMO channel capacity and diversity performance in wireless communications, more effective and suitable models that account for real antenna radiation behavior have to be taken into account. One of the main challenges is the accurate modeling of antenna correlation that is directly related to the amount of channel capacity o...
