A Simulation Research on Combined Denoising Algorithm Based on Adaptive Line Enhancement

Aim at the inadequate of traditional adaptive line enhancement algorithm, a new LMS algorithm with output feedback is put forward in this paper. The new filter output is constituted by the current output and the past output, then constitute a new filter. The simulation result shows that the new algorithm is better than the original algorithm in time domain waveforms, and the performance of the noise reduction is verified.
