Some New Results on Information Transmission Over Noisy Channels

Demonstratio Mathematica, 2015
Information transmission over communication channels has been characterized by weighted information schemes involving probabilities and weights. Binary erasure channel has been used as an example for determination of constants in the proposed measure.

Finding the Best QoS Path in a Gilbert Channel Network [PDF]

, 2008
Many different types of modern wired and wireless communication links can be mathematically described as discrete- time Gilbert channels. In this extended abstract, we present an exact method of calculating the best path in a network of discrete- time ...

Codes for the Quantum Erasure Channel [PDF]

, 1996
The quantum erasure channel (QEC) is considered. Codes for the QEC have to correct for erasures, i. e., arbitrary errors at known positions. We show that four qubits are necessary and sufficient to encode one qubit and correct one erasure, in contrast to

Timely Updates over an Erasure Channel [PDF]

, 2017
Using an age of information (AoI) metric, we examine the transmission of coded updates through a binary erasure channel to a monitor/receiver. We start by deriving the average status update age of an infinite incremental redundancy (IIR) system in which ...

Analysis for rank distribution of BATS codes under time-variant channels

Dianxin kexue, 2022
As a two-step coding technique applied in multi-hop networks with a low complexity, the transmission performance of batched sparse (BATS) code was directly related to the rank distribution of the transfer matrix.Based on the assumption that the packet ...

On the Oblivious Transfer Capacity of the Degraded Wiretapped Binary Erasure Channel

, 2015
We study oblivious transfer (OT) between Alice and Bob in the presence of an eavesdropper Eve over a degraded wiretapped binary erasure channel from Alice to Bob and Eve.

The quantum capacity is properly defined without encodings [PDF]

, 1998
We show that no source encoding is needed in the definition of the capacity of a quantum channel for carrying quantum information. This allows us to use the coherent information maximized over all sources and and block sizes, but not encodings, to bound ...

An Integer Erasure Correction Coding and Its Application for Security Enhancement of Encryption

IEEE Access
This paper presents a new class of erasure-correcting codes (ECCs) aimed at enhancing cryptographic security of certain encryption schemes. The proposed ECCs employ integer arithmetic to encode and decode data bits and can correct all data bytes, each ...
