A data reception, receiving method, computer program and corresponding recording medium

The invention relates to a data receiving device in a communication network using a plurality of radio frequency channels, at least two adjacent radio-frequency channels being concatenated to form a concatenated channel. Said apparatus comprises: - data receiving means transmitted in at least one radio frequency channel of said concatenated channel, said received data, - filtering means comprising at least two separate filter channels, each filter path comprising a band-pass filter whose frequency band corresponds to the frequency band of a separate radio frequency channel of said concatenated channel, such that the overall frequency band of said filters is equal to the frequency band of said concatenated channel, - means for activating at least one of said filtering channels, for filtering said received data.
