摘要：
In this paper, the performance analysis of the adaptive line enhancer when the input signal consists of multiple sinusoids embedded in noise is investigated. The performance is evaluated in terms of the signal-to-noise ratio gain at the filter's output. It is shown that, for multiple sinusoids, this gain is not only a function of the filter length, but also of three additional factors - the number of sinusoids, the noise power, and the amplitude of each sinusoid. Simulation results for a dual noisy sinusoidal input are presented to illustrate the validity of this analysis. (C) 2002 Elsevier Science BY. All rights reserved.
