This paper proposes a simple and efficient FPGA-based architecture of the overlapping/\nwindowing and overlap-add methods for real-time FFT/IFFT-based signal processing algorithms.\nThe analyzed signal is divided into short-time overlapping frames that are windowed before applying\nFourier analysis/synthesis. Then, the original signal is reconstructed from the windowed (modified)\nframes using the overlap-add (OLA) technique. The proposed architecture was implemented on Field\nProgrammable Gate Array (FPGA) using a high-level programming tool in MATLAB/SIMULINK\nenvironment. Its performance was evaluated on artificial and actual signals using objective metrics.
