Claim Text:
1. A method for receiving a signal that is transmitted after being modulated by a continuous phase modulation, said modulated signal being able to be broken down in a form of a sum of a plurality of amplitude-modulated signals, each amplitude-modulated signal being able to be expressed in a form of a product between a complex pseudo-symbol and a temporal component with a waveform predefined according to parameters of the continuous phase modulation, said method comprising a step of: implementing, at a receiver, a filter bank, the filter bank being generated with the steps of: evaluating, over a duration (T) that is equal to a duration of a symbol, all waveforms of the modulated signal from the parameters of the continuous phase modulation and a breakdown in the form of the sum of the plurality of amplitude-modulated signals, the evaluating including at least determining all values of the complex pseudo-symbols, retaining all the evaluated waveforms that are different from one another, and constructing the filter bank made up of a plurality of filters whose temporal responses are equal to the retained waveforms, said retained waveforms being limited to a duration equal to the duration of the symbol; and demodulating, at the receiver, the modulated signal upon filtering by the filter bank.
