摘要： A method for quantizing a signal on a regular two-dimensional hexagonal lattice by combining points in a two-dimensional space with the values taken by the signal, applying an origin-centred homothety to each point so that all the homothetic points are located within a reference hexagon, determining the points that are closest to the homothetic points and located on said hexagonal lattice, and encoding the co-ordinates of said points of the hexagonal lattice. Said reference hexagon is an origin-centred hexagon rotated through pi /6 rad relative to the Voronoi regions of said hexagonal lattice.

摘要： A multicarrier signal to be transmitted to digital receivers, particularly in a non-stationary transmission channel, corresponding to the frequency multiplexing of a plurality of elementary carriers each corresponding to a series of symbols is described, wherein two consecutive symbols are separated by a symbol time tau 0. The spacing nu 0 between two adjacent carriers in the signal is equal to half the reciprocal of the symbol time tau 0 and each carrier is subjected to spectrum formatting filtering with a bandwidth which must exceed twice the intercarrier spacing nu 0, and selected so that each symbol is highly concentrated in the time and frequency domain. Methods for transmitting and receiving such a signal are also described.

摘要： 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.

摘要： In order to attain subjectively pleasant listening even when reception is poor with frequent muting, in the case of digital radio transmission, the level of the sound signal received is gradually decreased. When reception is improved such that, only by using error correction and error masking, the reproduced sound signal is felt not to be unpleasant, the level of the sound signal is gradually increased again to the normal value.
