Abstract:
1. A method for signal processing operating on overlapped frames of a time-domain input signal, said method comprising the steps of: performing time-domain aliasing (TDA) based on an overlapped frame, having a length 2N, to generate a corresponding time-domain aliased frame having a length N; performing segmentation in time based on the time-domain aliased frame of length N to generate at least two overlapped segments by producing a frame having a length larger than N based on the time-domain aliased frame and then dividing the resulting produced frame into overlapped segments each having a length equal to or smaller than N; and performing spectral analysis based on said at least two overlapped segments by applying, on each of said at least two overlapped segments, a transform adapted for the segment to obtain, for each segment, a corresponding set of coefficients representative of the frequency content of the segment.
