05 Nov 2007TL;DR: The potential use of radio over fiber techniques is analyzed and discussed in the context of recent large scale optical fiber deployments in Europe for broadband access but as well in thecontext of home or in-building networks to provide very high data rates to the end-users in harmony with expected evolution of broadband connections.
Abstract: The potential use of radio over fiber techniques (RoF) is analyzed and discussed in the context of recent large scale optical fiber deployments in Europe for broadband access but as well in the context of home or in-building networks to provide very high data rates to the end-users in harmony with expected evolution of broadband connections. Main challenges for RoF include the current evolution toward an all IP network, the rapidity with which networks evolve and the lack of standardization work.

05 Sep 2004TL;DR: To evaluate the fluctuations of the UWB channel, a propagation experiment has been conducted in the 3.1 - 11 GHz frequency band, involving different antenna locations and moving people, and the presented results emphasize the difference between the spatial and temporal channel variability.
Abstract: Comprehensive modelling of the ultra-wide band (UWB) radio channel necessitates a good knowledge of its fading statistics. To evaluate the fluctuations of the UWB channel, a propagation experiment has been conducted in the 3.1 - 11 GHz frequency band, involving different antenna locations and moving people. The presented results emphasize the difference between the spatial and temporal channel variability, and provide a practical assessment of the UWB signal fading distribution in the case of a dynamic environment.

29 Oct 1991TL;DR: In this article, a binary encoding method was proposed for the encoding of data elements designed to be represented sequentially, according to a preestablished order, for example in counters, inducing a uniform or substantially uniform mean changing rate for each of the binary elements, the data elements being encoded on two distinct fields of binary elements.
Abstract: A binary encoding method notably but not exclusively for the encoding of data elements designed to be represented sequentially, according to a preestablished order, for example in counters, inducing a uniform or substantially uniform mean changing rate for each of the binary elements, the data elements being encoded on two distinct fields of binary elements, a reference field and a permutation field, and the sequence of binary elements assigned to the permutation field undergoing a permutation as a function of the value contained in the reference field.

17 Nov 2009TL;DR: In this article, a hierarchical coding method for hierarchical coding of a digital audio signal comprising of a core coding and an enhancement coding is presented. But the coding method can also include a shaping of the coding noise for the core bitrate coding.
Abstract: A method is provided for hierarchical coding of a digital audio signal comprising, for a current frame of the input signal: a core coding, delivering a scalar quantization index for each sample of the current frame and at least one enhancement coding delivering indices of scalar quantization for each coded sample of an enhancement signal. The enhancement coding comprises a step of obtaining a filter for shaping the coding noise used to determine a target signal and in that the indices of scalar quantization of said enhancement signal are determined by minimizing the error between a set of possible values of scalar quantization and said target signal. The coding method can also comprise a shaping of the coding noise for the core bitrate coding. A coder implementing the coding method is also provided.
