Why We Can Not Surpass Capacity: The Matching Condition
Iterations coding system coding binary input
2015/8/21
We show that iterative coding systems can not surpass capacity using only quantities which naturally appear in density evolution. Although the result in itself
is trivial, the method which we apply s...

The Capacity Region of a Class of Deterministic Interference Channels.
The capacityregion is establishedfor those discrete memoryless broabst channel.9p(y,t~x) for wbicb Z(X; Y) >Z(X; Z) holds for au input distributions. ‘ l%e capacity region for this class of channels r...
The Feedback Capacity of Degraded Broadcast Channels
Feedback Capacity Degraded Broadcast Channels
2015/8/12
e fact that the capacity region of the discrete memoryless physically degraded broadcast channel is not increased by feedback is establisked.
In this note, we investigate the conditions under which Borel-Cantelli Lemma holds of Choquet capacity, which is a reasonable generalization of traditional Borel-Cantelli Lemma of probability measure
A general central limit theorem for capacity
G-expectation G-distribution generalized G-expectation capacity tightness CLT
2011/11/4
In this paper,in the base of sublinear expectation space called 'G-expectation space' that introduced by Peng , adapting Peng's IID notion and applying Peng's new CLT under sublinear expectations, we ...
A note on the Triple Product Property subgroup capacity of finite groups
Triple Product Property finite groups Group Theory
2011/9/23
Abstract: In the context of group-theoretic fast matrix multiplication the TPP capacity is used to bound the exponent $\omega$ of matrix multiplication. We prove a new and sharper upper bound for the ...
Mass-capacity inequalities for conformally flat manifolds with boundary
Mass-capacity inequalities conformally flat manifolds boundary
2011/8/29
Abstract: In this paper we prove a mass-capacity inequality and a volumetric Penrose inequality for conformally flat manifolds, in arbitrary dimensions. As a by-product of the proofs, capacity and Ale...
SNEED: Enhancing Network Security Services Using Network Coding and Joint Capacity
Network Security Services Network Coding Joint Capacity
2011/3/3
Traditional network security protocols depend mainly on developing cryptographic schemes and on using biometric methods. These have led to several network security protocols that are unbreakable based...
On the Capacity of Memoryless Finite-State Multiple-Access Channels with Asymmetric State Information at the Encoders
multiple-access channe
2011/1/19
A single-letter characterization is provided for the capacity region of finite-state multiple-access channels,when the channel state process is an independent and identically distributed sequence.
Towards the Capacity Region of Multiplicative Linear Operator Broadcast Channels
Capacity Region Multiplicative Linear Operator Broadcast Channels
2011/2/28
Recent research indicates that packet multicasting employing random linear network coding can be regarded as transmitting subspaces as codewords over a linear operator channel (LOC).
A new problem formulation is presented for the Gaussian interference channels (GIFC) with two
pairs of users, which are distinguished as primary users and secondary users, respectively. The primary u...

Capacity Discrete Memoryless Broadcast Feedback
2011/3/1
A coding scheme for the discrete memoryless broadcast channel with {noiseless, noisy, generalized} feedback is proposed, and the associated achievable region derived.
Ito diffusions, modified capacity and harmonic measure. Applications to Schrodinger operators
Absolutely continuous spectrum Schr¨odinger operator
2011/2/22
We observe that some special Itˆo diffusions are related to scattering properties of a Schr¨odinger operator on Rd, d 2. We introduce Feynman-Kac type formulae for these stochastic processes wh...
