효율적 리셋 기법을 이용한 VSS-SA 기반 적응 푸리에 분석 알고리즘

Abstract

This paper proposes an adaptive Fourier analysis algorithm using VSS-SA robust against impulsive noise along with an efficient reset method. Specifically, for the adopted reset method in the proposed algorithm, the error variance estimates obtained for the step-size update are reused to set the control variable without employing additional variables. Computer simulation results show that the proposed algorithm requiring lower computational complexity yields the same robust convergence performance for adaptive Fourier analysis as the conventional algorithm.
