Abstract
Based on the least mean squares (LMS) algorithm,the LMS spectrum analyzer can be used to recursivelycalculate the discrete Fourier transform (DFT)of a sliding window of data. In this paper, we comparethe LMS spectrum analyzer with the straightforward nonadaptiveimplementation of the recursive DFT. In particular,we demonstrate the robustness of the LMS spectrumanalyzer to the propagation of round-off errors, a propertythat is not shared by other recursive DFT algorithms.I.
