In the paper, a theoretical work is done for investigating effects of splitting data sequence into packs of data set. We proved that a partitioning of data sequence is possible to find such that the e...
Convergence Rate Analysis of Distributed Gossip (Linear Parameter) Estimation: Fundamental Limits and Tradeoffs
Convergence Rate Analysis Fundamental Limits and Tradeoffs
2010/11/12
The paper considers gossip distributed estimation of a (static) distributed random field (a.k.a., large scale unknown parameter vector) observed by sparsely interconnected sensors, each of which only ...
Group-Decodable Space-Time Block Codes with Code Rate > 1
Group-Decodable Space-Time Block Codes math
2010/11/19
High-rate space-time block codes (STBC with code rate > 1) in multi-input multi-output (MIMO) systems are able to provide both spatial multiplexing gain and diversity gain, but have high maximum like...
Average Sum-Rate of Distributed Alamouti Space--Time Scheme in Two-Way Amplify-and-Forward Relay Networks
Average Sum-Rate Distributed Alamouti Space--Time Scheme Amplify-and-Forward Relay Networks
2010/11/11
In this paper, we propose a distributed Alamouti space-time code (DASTC) for two-way relay networks employing a single amplify-and-forward (AF) relay. We first derive closed-form expressions for the ...
The rate of the convergence of the mean score in random sequence comparison
the mean score random sequence comparison
2010/11/18
We consider a general class of super-additive scores measuring the similarity of two independent sequences of $n$ i.i.d. letters from a finite alphabet. Our object of interest is the mean score by le...
Convergence in $L^p$ and its exponential rate for a branching process in a random environment
branching process random environment
2010/11/9
We consider a supercritical branching process $(Z_n)$ in a random environment $\xi$. Let $W$ be the limit of the normalized population size $W_n=Z_n/E[Z_n|\xi]$. We first show a necessary and sufficie...
Nonequilibrium fluctuations for a tagged particle in one-dimensional sublinear rate zero-range processes
Nonequilibrium fluctuations tagged particle one-dimensional sublinear rate zero-range processes
2010/11/11
Nonequilibrium fluctuations of a tagged, or distinguished particle in a class of one dimensional mean-zero zero-range systems with sublinear, increasing rates are derived. In Jara-Landim-Sethuraman (2...
Robust Rate-Maximization Game Under Bounded Channel Uncertainty
Robust Rate-Maximization Channel Uncertainty
2010/11/12
We consider the problem of decentralized power allocation for competitive rate-maximization in a frequency-selective Gaussian interference channel under bounded channel uncertainty. We formulate a dis...
Positive Steady States of A Prey-predator Model with Diffusion and Non-monotone Conversion Rate
A prey--predator model Steady states Existence Uniqueness Stability
2007/12/11
In this paper, we study the positive steady states of a prey--predator model with diffusion throughout and a non-monotone conversion rate under the homogeneous Dirichlet boundary condition. We obtain ...
