Space Time relaying versus Information Causality
نویسنده
چکیده
We investigate the connection between causality and Information Theory. We show that a simple reading of Information Theory makes that quantum entanglement allows super-luminal information transfer. We show that introducing the concept of space-time information relaying partially solves the paradox of non causal information transfer. Surprisingly information causality is only dependent on the quantum unitarity which is a weaker principle than physical causality.

Nous montrons qu’une lecture basique de la théorie de l’information peut amener à d’crire le phénomène quantique d’intrication comme un transfers d’information super-luminique. Nous montrons comment l’introduction du concept de routage spatio-temporel résoud partiellement ce paradoxe de transfers d’information non causal. De manière surprenante la causalité del’information dépend du principe d’unitarité quantique, celui-ci étant un principe physique plus faible que celui de la causalité.

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...
متن کاملOptimizing Time and Power Allocation for Cooperation Diversity in a Decode-and-Forward Three-Node Relay Channel
Providing space diversity at mobile devices such as handsets, personal digital assistants (PDA), etc is costly and problematic, due to their strict space limitation. Recent studies, however, have revealed that extraordinary diversity gain, which results in the remarkable bene ts of an increased achievable transmission code-rate and a reduced information outage probability, can be obtained fro...
متن کاملRelay-Assisted Distributed Hybrid MIMO Transceiver with Information Exchange Errors for Cooperative Networks
-For non-relaying cooperative networks, the previous work proposed a distributed space-time block code (STBC) scheme considering information exchange errors in two-user cooperative networks. We propose a distributed Hybrid multiple-input multiple-output (MIMO) Transceiver scheme (HMT) considering information exchange errors in three-user cooperative networks. For relaying cooperative networks, ...

T his empirical analysis endeavors to trace out the causal nexus between core inflation and economic growth from the perspective of twenty worlds’ leading economy with the help of the nonlinear Granger causality approach by using time series data from 1981 to 2016. Based on nonlinear Granger causality results, it has been found that there is unidirectional casualty running from core ...
متن کاملCooperative MIMO Relaying with Orthogonal Space-Time Block Codes in Wireless Channels with and without Keyholes
Cooperative multiple-input multiple-output (MIMO) relaying is investigated in the paper. We introduce DFAF selection MIMO relaying, where the relay equipped with multiple antennas can adaptively switch between decode-and-forward (DF) and amplify-and-forward (AF) according to its decoding state of the sourcemessage. We consider two wireless environment scenarios: 1)The scenario with traditional ...
