Abstract

•Only two non-recursive efficient algorithms for the STDFT was known until now.•The paper presents another similar algorithm with less computational cost.•The pseudo code for this new best-so-far algorithm is included in the paper.

This work presents a radix-4 decimation-in-frequency algorithm for the efficient computation of the short-time, discrete Fourier transform, which makes use of radix-4 butterflies with time-varying coefficients arising from a fixed time origin.The proposed scheme is successfully compared with existing competing algorithms in terms of computational cost.
