Abstract :
The paper presents a multichannel weighted overlap-add (WOLA) algorithm applied to sub-band signal processing in hydroacoustic monitoring tasks. WOLA is illustrated as a multichannel filter bank implementation in terms of block-by-block signal analysis using vector discrete Fourier transform. Software implementation in MATLAB is discussed and the computation times are provided.
