Abstract: A method for the dynamic reconfiguration of a signal frame structure, wherein each frame is structured in at least one subchannel having a number, order and/or format capable of being altered under the control of a reallocation command, time interleaving on N frames being selectively performed for each subchannel. According to the method, in the transient state, and for the N frames following a reallocation command, the procedure for writing data elements according to the interleaving law remains unchanged, in accordance with the new structure defined by a reallocation command, and a specific logic for rereading the memory plane is implemented so that the frames consist of uniform capacity units comprising data elements from the same source signal. The corresponding transmitters, receivers and signals are also disclosed.

Abstract: A method for the broadcasting of digital data, intended to be received notably by mobile receivers moving about in an urban environment, that is, under conditions of multiple propagation and in the presence of parasites and jamming, enabling a coherent demodulation under such conditions of reception. This method is one for the broadcasting of digital data, notably for radio broadcasting at a high bit rate towards mobile receivers, of the type providing for the distribution of the data in the form of digital elements in the frequency-time space f-t and the transmission of symbols each constituted by a multiplex of N orthogonal carrier frequencies modulated by a set of digital elements and broadcast simultaneously, certain of the digital elements being reference elements with a value and position in the frequency-time space f-t that are known to the receivers.
