Abstract: Fast Fourier Transform (FFT) algorithms play a fundamental role in modern digital signal processing (DSP). A composite length FFT decomposes a longer-length FFT into multiple shorter-length ...
Abstract: In order to solve the contradiction between real-time spectrum analysis and resource limitation in embedded audio processing, this paper proposes an efficient FFT algorithm based on mixed ...
Though the FFT algorithm is brilliant---both extremely fast and efficient---it is still limited by the size of the computer's memory. But we can extend the standard Cooley-Tukey algorithm to work on ...
