Receiver multi - standard and brief description of the associated

摘要

The invention relates to a method for processing at least one received analogue signal χi, i=1 to M, comprising a plurality of N channels of interest Cij, where j=1 to N, having a frequency width Δfij over a given frequency band Δfi, M being an integer greater than or equal to one, N being an integer greater than or equal to 2, the method comprising the following steps: - digitising the received analogue signal to provide a digital signal Xi; - application of a WOLA algorithm to the digital signal Xi to provide a time frame yi(k) of length Kp, Kp being an integer greater than or equal to N; - filtering of each element of the time frame yi(k) where k=1..., Kp, at least N Goertzel filters operating in parallel, each filter being centred on a central frequency of a channel of interest Cij, the filtering being performed to extract a plurality of sub-bands Sij each centred on the central frequency of a channel of interest Cij and having a width greater than that of the corresponding channel of interest Cij.
