WebFFT DSL is FFTW [5], which is the most widely used open-source FFT library. At its heart, FFTW is an FFT compiler, based on Objective Caml, to generate Directed Acyclic Graphs (DAG) of FFT algorithms and performs algebraic optimization on them. FFTW uses a planner at runtime to recursively decompose the DFT problem into sub-problems. These … WebJun 1, 2024 · rtl_power_fftw. rtl_power_fftw is a program that obtains a power spectrum from RTL devices using the FFTW library to do FFT. It is inspired by the program rtl_power in librtlsdr. However, the said program has several deficiencies that limit its usage in demanding environments, such as radio astronomy. An inspection of rtl_power in hope of ...
