Abstract：A spectral-line enhancement algorithm based on linear combination is applied to denoise the narrow vibration signal. Aim at the disadvantage of traditional adaptive spectral-line enhancement algorithm, a new LMS algorithm with output feedback is brought out in this paper., which comprise the historic information output by filter and the output by the linear combination to form the new output. So a new algorithm is set up. The effect of the combination filter is researched with Matlab simulation. The simulation and actual signal is applied in the simulation. From the results of simulation, it can be concluded that the new algorithm is better than the original algorithm in time domain waveforms, and the performance of the noise reduction is verify.
