TL;DR: In this paper, a method for the broadcasting of digital data, in channels to which multiple paths are assigned, the characteristics of which vary in time, with time-frequency interlacing and assistance in the acquisition of the automatic frequency control is presented.

TL;DR: In this article, a spectrum of spectral lines separated by low spectral power density intervals is used for digital broadcasting of a sound program in a channel of a set of channels, and the digital signal is recovered by comb filtering on reception.

TL;DR: In this article, a method for the transmission of digital data elements including radio paging information elements, wherein the data elements are transmitted according to a technique of transmission implementing a plurality of orthogonal carrier frequencies (the COFDM technique), the signal being organized in frames comprising, firstly one first channel called a fast information channel, comprising at least one symbol of data elements, the carrier frequencies of the symbols being modulated by data elements that are not temporally interleaved.

TL;DR: In this article, the reception of digital data broadcast at a high bit rate for reception by mobile receivers is described under adverse conditions of multiple propagation corresponding to the Rayleigh process and imperfect frequency tuning to minimize the inter-symbol interference in the frequency domain.

TL;DR: In this article, the authors proposed a two-stage analogue synchronisation system for broadcasting of digital data intended to be received in particular by mobile stations travelling in an urban environment that is to say in the presence of disturbances and interference, and under multi-propagation conditions.
