TL;DR: In this article, cooperative luminescence is used as a defining process for ions cluster which can help to distinguish them from energy transfer processes and so to separate processes occurring at different distances.

TL;DR: This letter reports an experimental demonstration of an indoor angle-diversity optical wireless communications system that operates at 1.25 Gb/s and provides bidirectional communications between two terminals.
Abstract: This letter reports an experimental demonstration of an indoor angle-diversity optical wireless communications system. This operates at 1.25 Gb/s and provides bidirectional communications between two terminals. Each terminal uses three transmitting "cells" giving a field of view of approximately 25° × 8° over a range of approximately 3 m. Data is transmitted to a terminal that uses three receivers to obtain a similar reception field of view. Link operation at a bit-error rate <;; 10e-9 is reported, together with an overview of the system configuration.

TL;DR: In this paper, a method and device for the convolutional coding of data blocks, each consisting of a predetermined number N of source data, wherein each of said source data is input twice in the same CNN implementing an L period generator polynomial, in an order such that the two inputs of the same source data di are separated by the input of (pi.
Abstract: A method and device for the convolutional coding of data blocks, each consisting of a predetermined number N of source data, wherein each of said source data is input twice in the same convolutional coder (22) implementing an L period generator polynomial, in an order such that the two inputs of the same source data di are separated by the input of (pi.L)-1 other source data, pi being an integer other than zero. The invention also discloses a corresponding decoding method and device. It is particularly useful for transmitting short messages, for example in radiotelephone, satellite communication or computerised telecommunication (such as the Internet network) applications.

TL;DR: In this paper, a framework for enabling or enhancing a use of voice control in a voice controlled application (VCA) via a development framework is presented. And an associated development system for developing the VCA and user equipment that executes the V CA are provided as well.
Abstract: A method is provided for enabling or enhancing a use of voice control in a voice controlled application (VCA) via a development framework. The method includes: providing in the framework a plurality of action-context pairs—also called framework action-context pairs—usable in a memory of an application development device, which includes a processor, that serve to direct execution of the VCA, wherein the framework context defines a list of parameters related to the action and their respective value types; providing at least one of a voice recognition engine (VRE) and a natural language library to match each action-context pair with semantically related vocabulary; providing in the framework a registration mechanism that permits an association to be formed between an action-context pair and a handler in the voice controlled application. An associated development system for developing the VCA and user equipment that executes the VCA are provided as well.

TL;DR: In this article, a method for speech/non-speech detection using a linear discriminant analysis (LDA) applied to mel frequency cepstrum coefficients (MFCC) is presented.
Abstract: In speech recognition, speech/non-speech detection must be robust to,noise. In the paper, a method for speech/non-speech detection using a linear discriminant analysis (LDA) applied to mel frequency cepstrum coefficients (MFCC) is presented. The energy is the most discriminant parameter between noise and speech. But with this single parameter, the speech/non-speech detection system detects too many noise segments. The LDA applied to MFCC and the associated test reduces the detection of noise segments. This new algorithm is compared to the one based on signal to noise ratio (Mauuary and Monne, 1993).
