Abstract:
1. Method for receiving an ultra-wideband signal representative of symbols, this signal being transmitted over a transmission channel comprising, over a symbol time, a series of modulated successive direct pulses, each direct pulse being propagated along at least one direct propagation path, and each direct pulse being associated with a plurality of separate successive secondary pulses which are each propagated along a secondary propagation path, that method comprising: receiving the series of modulated successive direct pulses and the plurality of secondary pulses associated with each of the modulated successive direct pulses being received on the same receiving circuit, producing a composite correlation pattern which is constituted by a series of elemental correlation patterns comprising first elemental correlation pattern which is associated with each direct pulse and successive elemental correlation patterns which are each associated with a successive secondary pulse, calculating the value of a global intercorrelation coefficient, which allows a global correlation value to be obtained for the symbol, the calculating comprising i) calculation of the elemental intercorrelation coefficient between each elemental intercorrelation pattern and the direct pulse or secondary pulse associated with each of elemental intercorrelation patterns, and ii) integration, over the symbol time, of the group of elemental intercorrelation coefficient values in order to transmit the global intercorrelation coefficient value which represents the global correlation value of the symbol.
