Frequency mismatch in narrowband active noise control
ICASSP（2010）
摘要
This paper analyzes the effects of frequency error in internal signal generator for narrowband active noise control systems. Two stability conditions and the optimum step-size to achieve the minimum excess mean-square error are analyzed in the paper. The noise reduction is formulated as a function of frequency mismatch, step size, and phase error in the estimation of the secondary path. The theoretical analysis presented in the paper is verified by computer simulations.
