Exponential Strong Converse for One Helper Source Coding Problem [PDF]

, 2019
We consider the one helper source coding problem posed and investigated by Ahlswede, Körner and Wyner. Two correlated sources are separately encoded and are sent to a destination where the decoder wishes to decode one of the two sources with an ...

Hybrid Adaptive Video Steganography Scheme Under Game Model

IEEE Access, 2019
The steganographic model based on game theory is improved. A hybrid steganography model that satisfies the Kerckhoffs principle by combining the strategy adaptation of the game theory model and the content adaptation in the cover model is proposed.

Error detection and correction for coding theory on k-order Gaussian Fibonacci matrices [PDF]

, 2023
In this study, the coding theory defined for k-order Gaussian Fibonacci polynomials is rearranged by taking x =1. We call this coding theory the k-order Gaussian Fibonacci coding theory. This coding method is based on the Qk,Rk and En(k ) matrices.

Chaos communication performance : theory and computation [PDF]

, 2010
In this paper new and existing approaches are developed to compute the bit error rate for chaos-based communication systems. The multi-user coherent antipodal chaos shift keying system is studied and evaluated in its coherent form, in the sense of ...

Subset Vector Perturbation Pre-Coding for MU-MIMO Downlink Systems

IEEE Access, 2018
Multi-user multiple input multiple output (MU-MIMO) is a basic technique which has been widely investigated for its ability to increase system capacity. However, the inter-user interference (IUI) is one of the obstacles to obtain system capacity.

A Decoding Algorithm for LDPC Codes Over Erasure Channels with Sporadic Errors [PDF]

, 2010
An efficient decoding algorithm for low-density parity-check (LDPC) codes on erasure channels with sporadic errors (i.e., binary error-and-erasure channels with error probability much smaller than the erasure probability) is proposed and its performance ...

ANALYSIS OF THE KNOWN METHODS OF CHANNELS COMMUNICATION CONTROL WITH THE INTERFERENCE AND SELECTIVE FADING

Сучасні інформаційні системи, 2019
Designing adaptive radio systems, depending on their purpose, solves the problem of optimizing one of the performance indicators with restrictions on others.

A dual role for prediction error in associative learning [PDF]

, 2009
Confronted with a rich sensory environment, the brain must learn statistical regularities across sensory domains to construct causal models of the world.
