In this paper an approach to joint source-channel coding (JSCC), named Shannon-Kotel’nikov mappings (SKmappings), is presented. SK-mappings are (piecewise) continuous direct source-to-channel mappings operating directly on amplitude continuous discrete time signals. A theory for calculating and categorizing the end-to-end distortion when using SK-mappings for communication is presented. The the...

The strengthened data processing inequality have been proved. The general theory have been illustrated on the simple example. Quantum information theory is a new field with potential applications for the conceptual foundation of quantum mechanics. It appears to be the basis for a proper understanding of the emerging fields of quantum computation, communication and cryptography [1-4]. Quantum in...

Multi-carrier CDMA technology is a very attractive multiple access technique for next generation wireless communication systems. It combines the advantages of both Orthogonal Frequency Division Multiplexing (OFDM) and Code Division Multiple Access (CDMA) for high data rate transmission. However, interference noise is considered as a major challenge for MC-CDMA systems and significantly affects ...

The herein approach addresses the case when the user is part of the communication channel. A purpose of the abstraction is to provide a framework for the field of communications, with the user included in the system, reckoning the current 7 Layer model allows safeguards for data only. Solid grounds for application were identified as contribution to ensuring the need for safety which becomes tig...

Accurate channel state information (CSI) is necessary at receiver for coherent detection in amplify-and-forward (AF) cooperative communication systems. To estimate the channel, traditional methods, that is, least squares (LS) and least absolute shrinkage and selection operator (LASSO), are based on assumptions of either dense channel or global sparse channel. However, LS-based linear method neg...

The field of coding theory emerged with the pioneering work of Claude E. Shannon “A Mathematical Theory of Communication”, published in 1948 in the Bell System Technical Journal. In his work, Shannon investigates both the transmission and compression of information. A probabilistic model is proposed for the communication channel or for the source, and a mathematical measure is proposed to quant...

this paper assumes the cell formation problem as a distributed decision network. it proposes an approach based on application and extension of information theory concepts, in order to analyze informational complexity in an agent- based system, due to interdependence between agents. based on this approach, new quantitative concepts and definitions are proposed in order to measure the amount of t...

Bennett et al. showed that allowing shared entanglement between a sender and receiver before communication begins dramatically simplifies the theory of quantum channels, and these results suggest that it would be worthwhile to study other scenarios for entanglement-assisted classical communication. In this vein, the present paper makes several contributions to the theory of entanglement-assiste...
